Question 10: How many 176 Ω resistors in parallel are required to carry 5 A on a 220 V line? It is not difficult to score full marks in a science exam if you know exactly how much to write. If the flow of current exceeds the specified preset value due to some reason, the heat produced melts it and disconnects the circuit or the device from the mains. Hence, when the length of wire is doubled, the resistance becomes double and current decreases to half.
