Physics Current Electricity Quick Notes

Before solving Physics Current Electricity PYQs, revise these key formulas:

  • Ohm’s Law:

V=IRV = IR V=IRV = IR

  • Power:

P=VI=I2R=V2RP = VI = I^2R = \frac{V^2}{R}

  • Series Combination:

R=R1+R2+R3R = R_1 + R_2 + R_3

  • Parallel Combination:

1R=1R1+1R2\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2}

  • Drift Velocity:

vd=InqAv_d = \frac{I}{nqA}

  • Kirchhoff’s Laws:
    Sum of currents at junction = 0
    Sum of voltages in loop = 0

These formulas are the backbone of most Physics Current Electricity PYQs.
