How to find current through each resistor?
The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A. Note that the sum of the potential drops across each resistor is equal to the voltage supplied by the battery.
With that being said, is the current the same through each resistor?The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: With a 10 V battery, by V = I R the total current in the circuit is: I = V / R = 10 / 20 = 0.5 A.
Given this, how do you calculate current through a resistor and voltage?You take the basic formula of E = I x R, solve for R -> R = E / I. In other words, take the required voltage drop (in volts) and divide by the current (in amps) in the resistor and determine the resistance (R) in ohms.
In the same way what is the current through the 3.0 Ω resistor?The current through the 3.0 Ω resistor is 2.0 A.

According to the Wikipedia online encyclopaedia, a 100 watt bulb is 2.1% efficient. In other words, it produces about 2 watts of light and 98 watts of heat. A halogen lamp is a bit better.
Current through each resistor can be found using Ohm's law I=V/R, where the voltage is constant across each resistor. The current flowing from the voltage source in Figure 10.3. 4 depends on the voltage supplied by the voltage source and the equivalent resistance of the circuit.

The formula is heat produced = voltage squared divided by resistance. In the question he found out the heat as 4 joule per second and then as given voltage was equal to 2 volts. Simply apply the formula.
Unlike lamps, they do not produce light, but they do produce heat as electric power is dissipated by them in a working circuit. Typically, though, the purpose of a resistor is not to produce usable heat, but simply to provide a precise quantity of electrical resistance.
When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat. the higher the current the larger the amount of heat generated.

A 100-watt incandescent light bulb has a filament temperature of approximately 4,600 degrees Fahrenheit.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
So the rate of heat transfer to an object is equal to the thermal conductivity of the material the object is made from, multiplied by the surface area in contact, multiplied by the difference in temperature between the two objects, divided by the thickness of the material.
To calculate the wattage requirement to heat steel, use the following equation:
- Watts = 0.05 x Lbs of Steel x ΔT (in °F) / Heat-Up Time (in hrs)
- Watts = 3.1 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)
- Watts = 165 x Gallons Per Minute X ΔT (in °F)
- Watts = 1.35 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)
According to Ohm's law, these three quantities are related by the equation V = I R V=IR V=IR.
They possess very different properties—incandescent bulbs rely upon metals, gas and heat, while CFL's rely more upon a reaction between the internal and outside materials. For these reasons, incandescent lights emit more heat energy than CFL's.
