Question

किसी विद्युत बल्ब में 220 वोल्ट पर 2v की धारा प्रभावित होती है तो फिलामेंट की प्रतिरोध होगा

Answer 1

Resistance of the circuit will be 110 ohm

Explanation:

Here unit of current is given v which will be A

We have given supply voltage at which bulb is working V = 220 volt

Current flowing in the circuit i = 2 A

We have to find the resistance of circuit

According to ohm's law we know that voltage = current ×resistance

So resistance R will be $R=\frac{V}{I}$

$R=\frac{220}{2}=110ohm$

So resistance of the circuit will be equal to 110 ohm
