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 will happen to the generator voltage when the load fluctuates in distribution board?
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
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 they was no resistance?
current would go to a maximum, (if there was voltage present), if there was no voltage, no current would flow. the only thing that would limit the current flow (if voltage is present) is the small resistance of the cables, but say there was no resistance it would be like in a short circuit maximum current would flow at the instant voltage is applied. that is why RCD's work as they should, you want the most amount of current to flow at once because otherwise if the current was limited it would not trip in time to stop someone getting electrocuted.
What will happen to voltage if resistance decreases?
Nothing, but the current will increase.
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
What would happen to current if the voltage is constant and the resistance is dounbled?
by the ohms law we can clearly say that the current is the ratio of voltage to the resistance.as the resistance is doubled the current should be halved.
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 the voltage when the collector current increases in a biased circuit?
it dies
How does the cut in voltage effects the output of a diode?
The cut in voltage is that voltage where after the current increase rapidly and it's value is different-2 for different type of semiconductor. for silicon it is 0.7 and for germanium it is 0.3 volt. It means if you made a diode from silicon than applied voltage below 0.7 volt will not able to flow current (if flow than it is in term of few micro ampere) . it means diode will stay in off mode and for germanium same things will happen and it will rest on off condition below 0.3 volt(applied).
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.
