High Resistance In A Circuit
Resistance is the measure of opposition to electric current.
High resistance in a circuit. If the source of current is a battery such as a 3 volts button cells the cells will last for a longer time. Low resistance in the c. A high electrical resistance of an electrical conductor is the opposition to the flow of an electric current through that conductor. No technology located in a circuit breaker or fuse panel could detect a high resistance wiring fault as no measurable characteristic exists that differentiates a glow fault from normal branch circuit.
A high resistance in the circuit means a very low current flowing in it when the voltage of the source is constant. High electrical resistance is the opposition to current flow within a circuit. Short circuits are dangerous with high voltage power sources because the high currents encountered can cause large amounts of heat energy to be released. In the second example if circuit current is 3 amps instead of 4 circuit resistance has increased from 60 ω to 80 ω 240 3 80 ω.
The 20 ω gain in total resistance could be caused by a loose or dirty connection or an open coil section. The inverse measure is known as electrical conductance. The 60 ω resistance can help determine the condition of a circuit.
