Explanation:
Resistance R = V2/P, where V is the potential difference and P is the power in Watts. So, the more the power, the lower will be the resistance and vice versa. Or, R2 = 2R1. Thus, 25 W bulb will have double the resistance as compared to 50 Watt bulb
Answer:
Resistance R = V2/P, where V is the potential difference and P is the power in Watts. ... Thus, 25 W bulb will have double the resistance as compared to 50 Watt bulb.
