Question

a bulb draws a current of 0.5A from a cell of terminal potential difference 2V .find the resistance of the bulb
​

Answer 1

Answer:

we know that

volt=I(current)×R(resistance)

and 0.5=5/10ampere

2=5/10×Resistence

2×10=5×resistence

20/5=resistance

4ohm is resistance

please mark me as brainlist it is too important for me
