Question

Resistance of an electric bulb is 20 Ω. Calculate current flows through it, if

the voltage between two points is 30 V.​

Answer 1

Answer:

From Ohm's Law we know that

=> V = IR

where V = potential difference ; I = Current flowing and R = resistance

=> 20 = (A)(30)

=> A = 20/30 = 0.666.... A (or) 0.67A
