Question
On a constant-voltage battery the positive terminal is connected to one end of a resistor. The negative terminal is conncted to the other end. The basic circuit examined is:
Both the voltage and current are measured to be of different values on either side of the resistor.
The voltage is measured to be different values on either side of the resistor, but the current is measured to be the same.
The current is measured to be different values on either side of the resistor, but the voltage is measured to be the same.
Both the voltage and current are measured to of the same value on either side of the resistor.
How will the value of its resistance, R change when the voltage is doubled on the ends?
R will be half of its previous value.
R will be unchanged.
R will be twice its previous value.
Actual values of voltage and resistance are required to answer this question.
Both the voltage and current are measured to be of different values on either side of the resistor.
The voltage is measured to be different values on either side of the resistor, but the current is measured to be the same.
The current is measured to be different values on either side of the resistor, but the voltage is measured to be the same.
Both the voltage and current are measured to of the same value on either side of the resistor.
