# Why we specifically note resistance in a circuit while all part of a wire have some resistance..?

Why we specifically note resistance in a circuit while all part of a wire have some resistance..??? Answer: The resistance of the rest of the circuit compared to the resistance of the resistor is negligible. Incoming search terms:Why we specifically no...

# Electricity – Class X CBSE

Some important points to remember The resistance of a conductor does not change when the current through it is changed or the voltage across it is changed. When current is changed, the voltage across it is also changed so that the ratio V/I = R The value of resistance changes if the dimensions (length or … Continue reading Electricity – Class X CBSE

# Why the current through a conducting wire and a resistor are the same though the resistor has a greater resistance?

When a resistor is connected to a source using conducting wires, both are in series. The current through the wire as well as the resistor is determined by the total resistance of the circuit according to the relation V = IR Similarly, when a current is passed through a heating element, the connecting wires are … Continue reading Why the current through a conducting wire and a resistor are the same though the resistor has a greater resistance?
