Question

In the circuit on the right, a light bulb, two batteries, and five resistors are wired to form a circuit. For the following question, assume the color codes on resistors are not accurate (that is, use stated values) and assume each battery has 4.75 ? of internal resistance.

In the circuit on the right, a light bulb, two batteries, and five resistors are wired to form a circuit. For the following question, assume the color codes on resistors are not accurate (that is, use stated values) and assume each battery has 4.75 Ohm of internal resistance. If the internal resistance of the light bulb is 633 Ohm. calculate the power dissipation of the bulb.

Explanation / Answer

power=0.00223^2*633=3.14*10^-3 A
