Question

all formula's of lesson ELECTRICITY class 10 cbse

Answer 1

⭐ Hello Mate⭐
✔️Here is your answer ✔️

✨ Electric potential (V) = Work done/charge
✨ Electric current (I) = Charge/Time
✨ Potential difference= Work done/ charge
✨ Potential difference= Current× Resistance
✨ Resistance= Potential difference/Electric current
✨ Electrical resistivity= R×A/ L
✨ Parallel combination= 1/ Rp= 1/ R1+1/R2+1/R3....
✨Series combination= Rs= R1+ R2+ R3..
✨ Electric Power= V× I
✨ Amount of heat produced= I² × R × T
✨ Electrical energy= Power× Time

✌️Hope it helps you ✌️
☺️ Thank you ☺️

ANSWER.

☆☆ELECTRIC POWER FORMULAS: -
••• P = V I
••• P = R I^2
••• P = V^2 / R.
where P = Power.(watts)
V = Voltage(volts)
I = Current(Ampere)
R = Resistance (ohms)

☆☆☆ ELECTRIC CURRENT FORMULAS-
•• R = V/I
R = V^2/P
R = P/I^2

☆☆☆☆ ELECTRICAL POTENTIAL FORMULAS (ohms law):-
--- ohm' s law can be expressed as:
V = R I
V/I = R.
