Electricity

Introduction

Electricity is a form of energy produced by the movement of electric charges.

Electric Circuit

Components: Cell, Battery, Switch, Bulb, Resistor, Wires

Potential Difference

V = W/Q

  • (^) Unit: Volt (V)

Resistance

Opposes current flow.

  • (^) Depends on length, area, material and temperature.

Resistivity

R = ρL/A

  • (^) Unit: Ωm

Resistors in Parallel

Same voltage across each resistor.

Heating Effect of Current

Current flowing through a conductor produces heat.

Electric Power

P = VI

• P = I²R

• P = V²/R

Electrical Energy

E = Pt

  • (^) Commercial Unit: kWh

Exam Questions

Important short and long answer questions for revision.

Quick Revision

Current, Voltage, Resistance, Power, Energy, kWh
