A Flashlight That Is Powered By 3 Volts And Uses A Bulb With Aresistance Of 68. Will Have A Current Of

Answers

Answer 1
Start with the formula V = IR, where V is voltage, I is current, and R is resistance.

The voltage is 3 volts, so V = 3 volts

The resistance is 68 ohms, so R = 68 ohms

We don’t know I, which is the current in amps

Plug in what we know into the ohms law formula:

3 volts = I * 68 ohms

I = 3/68 = 0.044 Amps
