what is the power of torch bulb rated at 2.5V and 500 mA?
Asked by sunilgupta9419158173 | 20th Jul, 2021, 01:14: PM
P = VI
V = 2.5 V
I = 500 mA = 500 x 10-3 A
P = 500 x10-3 x 2.5 = 1.25 W

- The MCB of a Rupa’s room is tripped and keeps on tripping again and again. If it is a domestic circuit, what could be the reason of this phenomenon?
- a current
- if 20 C of charge pass a point in a circuit in 1 second what current is flowing
- an electric bulb is related220 V and 100 W when it is operated on 110 V the power consumed will be
- A coil draws a current of 1.0 ampere and a power of 100 watt from an A.C. source of 110 volt and 5√22/π hertz. Find the inductance and resistance of the coil. Why can't I use P=VI here, and how can I determine when to use P=VI or P=I^2 R or P=V^2 / R
- Is on every consecutive point the electric potential or potential difference is different or same at all points except the ends of conductor
- what is potential difference?
