Four resistances of 10 ohms, 4 ohms, 6 ohms and 5 ohms are connected in parallel. They are connected to a
battery which produces potential difference of 75 volts across its terminals. Find the: a) total resistance in the
circuit; b) total current in the circuit; c) current in each resistor; and d) voltage across each resistor.
