When measuring the resistance of a resistor using an ohmmeter, what does a reading of zero resistance indicate?
When using an ohmmeter, a reading of zero resistance indicates that there is no opposition to current flow, meaning the circuit behaves like a direct conductor. This condition is known as a short circuit.
In contrast, an open circuit would show infinite or very high resistance. A properly functioning resistor would show its rated resistance value. Therefore, zero resistance cannot indicate normal operation.
According to BIS SP 46-2003, which of the following applications is correctly represented by a chain-thin line in engineering drawings?
If the current flowing through a conductor is 5 A and the resistance of the conductor is 10 ohms, what will be the voltage across the conductor, according to Ohm's Law?
