Question

How can a lamp rated 12W 6V run on a 12V battery? explain.

Answer 1

please answer this I wanna know

Answer 2

Answer:

By a 6 Ohm resistor in the circuit.

Explanation:

To prevent the damage caused,one way is to insert a resistor of 6 ohm.This would make 2A of current to flow through the circuit which is the required amount of current.

As, P=VI

I =P/V=12/6=2A

and R=V/I

R=12/2=6 ohm

So if we insert resistance of 6 ohm in series to prevent damage.
