Question 11 (3 points)

1. How many amperes does a 125 watt bulb require when operating on 12 volts?

a. 0.096 watts
b. 10.41 Watts
С. 10.41 Ampere
D. 1500 ampere

Answer 1

С. 10.41 Ampere

Step-by-step explanation:

Given that,

Power, P = 125 watts

Voltage, V = 12 volts

We need to find current. Power in terms of current and voltage is given by :

P = VI, I = current

`I=(P)/(V)\\\\I=(125\ W)/(12\ V)\\\\I=10.41\ A`

So, the current is 10.41 A.
