A DC ammeter will read zero
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.
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 ()
The overall current will decrease by subtracting the current used by each device.
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
The purpose of an earthing (protective) conductor in a residential installation is to allow sufficient fault current to flow, in the event of an earth fault, to enable the operation of the circuit's overcurrent protection device (fuse or circuit breaker), so its resistance must be sufficiently low to allow this to 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.

Current through that part of the circuit will stop.
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.

Nothing will happen to circuit..... as usual the circuit would be supplying 220v(if india) and certain current...but there is no bulb to consume power...
it dies
Current stops flowing.
increase.
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.
The current in each branch of the circuit will turn and flow in the other direction.
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
