Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
how do you use ohms law express conductance in terms of current and voltage?
The current flowing through a conductor is directly proportional to the cross-sectional area of the conductor. This means that as the area of the conductor increases, the current flowing through it also increases, assuming the resistance and voltage remain constant.
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
It is halved. coz voltage=current * resistance
When the resistance is 960 ohms and the current is 2 amperes, we can use the formula for inverse variation: ( current \times resistance = constant ). Thus, ( 2 \times 960 = constant ), which is ( 1920 ). So, if the resistance changes to a new value, we can find the new current by dividing the constant by the new resistance.
Increasing the current in a circuit by a factor of 3 will increase the power by a factor of 9 (3^2), assuming the resistance remains constant. Power is directly proportional to the square of the current in a circuit with constant resistance, according to the equation P = I^2 * R.
If resistance is halved while voltage remains constant, the current will double.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
