Which of the following characteristics are true about a parallel circuit? 1. The current that goes through each resistor is the same. II. The drop in the voltage across each resistor is proportional to the resistance of that resistor. III. The current in the circuit is equal to the sum of the currents flowing in each part of the circuit. O I only O I and II III only OI and III .
