In a closed circuit what does an increase in voltage cause?
an increase in current, hence increased power and increased heat.
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
What will cause an increase in current flow in a simple series circuit?
Increase current by either increasing the voltage or decreasing the resistance.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
How does voltage cause flow in a circuit?
This causes flow because voltage is what powers a circuit
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
What is the function of emf in electric circuit?
An electromotive force is the potential difference developed by a voltage source, and is necessary to cause current to flow through a circuit. Strictly-speaking, it is the open-circuit potential difference of a battery, generator, etc. An alternative definition is that an e.m.f. is equal to the sum of the voltage drops around any closed loop, including any internal voltage drop.
What is supply and temperature independent biasing?
The signal or output of a circuit is often affected by changes in the supply voltage and/or ambient temperature. A biasing circuit is designed to consistently output a selected voltage (or current). Depending on the circuit topology, a change in supply voltage or temperature can cause the intended value to drift. In an increase in temperature can, for example, increase resistances in a circuit. Such effects are usually undesireable and thus a supply/temperature independent bias would be needed. Electronic component manufactures will frequently provide tolerances for outputs relative to changes in supply voltage and temperature.
What happens to the current in a circuit if the voltage is increased?
What are the changes to the resistance and the voltage will always increase the current in a circuit
Will you cause damage connecting ac current to a dc circuit?
It depends on the circuit. For example, providing the a.c. voltage is the same as the rated d.c. voltage, it would not harm a lighting circuit.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
