Respuesta :
increase it by a factor of 2 to change the applied voltage in a circuit if we want to increase the power by a factor of 4 by keeping the resistance constant.
Simple formula is:
Voltage (V) = Current (I) X Resistance (R)
Thu if R is constant and V is increased I will reduce
Thus assuming a constant Resistance , increasing the Voltage will reduce the current in the circuit.
Applied voltage :
Voltage applied to a circuit is equal to the sum of the individual voltage drops. The drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.
What happens when voltage is applied to a resistor?
Therefore, if the voltage is increased, the present will increase provided the resistance of the circuit does not change. Similarly, increasing the resistance of the circuit will lower the present flow if the voltage is not changed
Why is voltage applied?
When a voltage is applied, it's energetically preferable for an electric charge to move towards the point of lowest voltage in the wire; that's a fancy way of saying that a positive electric charge gains energy when going from a point of high voltage to a point of low voltage.
