A battery of emf 12 V is connected in series with three resistors of 2 Ω, 3 Ω and 5 Ω.
(i) Calculate the equivalent resistance of the 2 Ω, 3 Ω and 5 Ω resistors connected in series.
(ii) Determine the current in the circuit.
(iii) Find the potential difference across each resistor.
(iv) Verify that the sum of the three potential differences equals the battery emf.
