Question

Calculate effective resistance , current and potential difference between two resistors 10 ohm and 5 ohm connected in series

Answer 1

Let ​two resistors 10 ohm and 5 ohm connected in series with a battery of potential difference of V volts.

Equivalent resistance, R = R₁ + R₂ = 10 + 5 = 15 ohms

Current through both the resistances, I = V/R = V/15 amperes.

potential difference through resistor R₁ = 10 ohms is V₁ = I R₁ = (V/15) 10 volts.

potential difference through resistor R₂ = 5 ohms is V₂ = I R₂ = (V/15) 5 volts.
