What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
How to figure out ampreage in a circuit?
For a d.c. circuit, you divide its supply voltage by the resistance of its load. For an a.c. circuit, you divide its supply voltage by the impedance of its load.
How capacitor and resitor in a circuit effect the phase of input voltage?
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
The voltage for 4 bulbs in a circuit?
The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.
Which electrical test requires the supply to be energized?
Testing of an electrical circuit for voltage requires the supply to be energized.
What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.

If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?

What pushes the current around the circuit?
A voltage supply is needed to operate a circuit.
The voltage across a short circuit is equal to?
zero? the supply voltage? the supply voltage minus the individual coltage drops? the sum of the individual voltage drops? which one?
What is open circuit characteristic?
The terminal voltage is equal to the supply voltage and there is zero current.
How is the voltage of the power supply for a series circuit calculated?
The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.
What happens if the resistor in RC circuit is removed and the capacitor is directly connected to power supply?
If by power supply you mean a voltage source, it really won't matter that the resistor is removed. The voltage source will provide infinite current, instantly charging the capacitor so that the capacitor's voltage is equal to the source.Alternative AnswerIf you are referring to an a.c. circuit, then a load current will continue to flow with its value being determined by the capacitive reactance of the circuit, and the resulting phase angle will lead the supply voltage be very close to 90 degrees.
Block diagram of computer monitor?
chroma circuit, luminance circuit, picture tube, vertical and horizontal circuits, sync circuit, high voltage circuit, low voltage power supply
How is an open circuit dangerous?
its likely to have the full supply voltage across it
