What will happen to the power if you double both the current and the voltage in a circuit?

Explanation: If current is I and voltage is V , then resistance R=VI and power is given by P=V⋅I . As such when both the current and voltage in a circuit are doubled, resistance becomes R=2V2I=VI and hence remains same. −4V⋅I i.e. power becomes four times.

How do you find resistance with power and current?

For example if the power is 100 watts and the voltage is 50 volts, the current is 100 / 50, or 2 amps. Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current.

What happens to current when you add resistance?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

What happens to the current if the resistance is doubled?

The current is directly proportional to the voltage and inversely proportional to the resistance. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value.

What is the relationship of voltage current and resistance?

The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

Is resistance inversely proportional to power?

From here, we can see that the power P is inversely proportional to the resistance R. When the power in the circuit is high, resistance will be lesser. However, if the power is low, the resistance will be high.

Why power is inversely proportional to resistance?

power is inversly proportional to resistance as power is the rate of flow of electrical energy through a conductor with potential diff n more energy is used for more resistance.

How do you find resistance when given voltage and current?

From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).
