How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
What happen if you reduced the number of devices on each parallel circuit?
The overall current will decrease by subtracting the current used by each device.
What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
What would happen if a lamp was unscrewed from a parallel circuit?
There will be no change, because it is a parallel circuit.

When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
What happen when there is a break in the path circuit?
Current through that part of the circuit will stop.
What will happen if a piece of string is being used to complete a close circuit?
The piece of string will act as an insulator. Insulators will not carry circuit current when a voltage source is applied across it. Therefore nothing will happen if a piece of string is used to complete an electrical circuit.
When a low voltage current is applied to LCD screens what happen?
=== === === ===
What happen to the voltage when the collector current increases in a biased circuit?
it dies
When you add a resistor to a series circuit what will happen to the total current?
increase.
What will happen if part of the circuit is not properly connected?
Current stops flowing.
A lamp is connected to a battery if a capacitor is inserted in the positive wire between the battery and the lamp what will happen?
large capacitors will become charged in a fraction of a second if a DC voltage is applied to its terminalsonce a capacitor becomes fully charge it acts as an open circuit to direct current in other words, once the capacitor charged by a DC voltage, the current will cease to flow in the branch of the circuit which contains the capacitor.a capacitor also offers opposition known as (capacitive reactance) to alternating current. it does not , however ,act as an open circuit to when an a-c alternating current voltage is applied.
What happen to current in a circuit if the voltage in not charged but the resistant is double?
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
What happen if ac current is applied to dcmotor?
It will start giving a loud noise.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
