What is the difference between the inrush current and the fault current?
Magnetizing inrush current has bigger 2nd harmonics compare to short circuit current. the second harmonics content is about >60% of fundamental harmonic. magnetizing inrush current happened when we energised the transformer, and short circuit current happened if there is a short circuit between different alive phase.
If 3 A flows in a circuit for 2 hours. What is the charge flowing in the circuit?
Current, time are charge are related by the following equation: Q = It where Q = charge, I = Current, t = time in seconds so substituting the values, Q = 3 * ( 2 * 60 * 60) Q = 21,600 C
What is the induced voltage on a deenergized ungrounded circuit 60 feet from a 230000 volt circuit?
This question has not enough information for an answer. Is the 230 kV line overhead or underground? The voltage induced in a passive wire also depends on the amount of current in the high-power line.
What does 60hz alternating current do?
Direct current (DC) electrical power from a battery has no phase reversal of the electron flow in the electrical circuit. Electrons always flow from the negative terminal to the positive terminal of the battery in the wires of the circuit. In alternating current (AC), there is a periodic reversal of the flow of electrons (e.g. current) through the wires of the circuit. 60 Hertz refers to the frequency of that reversal of flow. 60 Hz is equal to 60 cycles per second. So AC current from your wall socket in the United States is reversing directions 60 times each second. The cycling is caused by design of the generators used in the power plants that produce the electricity. The current (polarity) reverses direction 120 times each second. Twice in each cycle on a 60 Hz system. Once to the positive and then once to the negative in one cycle.
What happens if you take away a load from a series circuit?
As an example imagine a 60 W light bulb running off 120 V. The current will be 1/2 A. Now assume that you put a second 60 W bulb in series with the first. Now the resistance of the single 60 W bulb is 240 Ohms. The 1/2 A flowing through the bulb heats up the filament wire and causes an amount of light to be emitted. Resistance in series adds, so the total resistance for two of the bulbs in series is 480 Ohms and by Ohms law V = I x R, the current through each bulb will be 1/4 amp and hence the bulbs will be less bright.
What is the resistance in a circuit that has a voltage of 60 V and a current of 2 A?
Ohm's law is V = I·R. You know V and I, so you can calculate R using R = V/I.60 V / 2 A = 30 Ω
What is the maximum current rating for the circuit breaker required for a 60 amp electrical load?
The maximum current rating for the circuit breaker needed for a 60 amp electrical load is 60 amps.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the current running through the 60 ohm resistor?
To calculate the current running through the 60 ohm resistor in a parallel circuit, you first need to find the total resistance of the circuit. For a parallel circuit, the reciprocal of the total resistance (1/RT) is equal to the sum of the reciprocals of the individual resistances (1/R1 + 1/R2 + 1/R3). Once you find the total resistance, you can use Ohm's Law (I = V/R) to calculate the current running through the 60 ohm resistor.
What is the maximum current rating for the circuit breaker in this electrical panel, specifically in relation to the keyword "60 amps"?
The maximum current rating for the circuit breaker in this electrical panel is 60 amps.
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
How much current does 60 watts Operated at 120 volts have?
To calculate the current, you can use the formula: Current (I) = Power (P) / Voltage (V). In this case, 60 watts divided by 120 volts equals 0.5 amperes. Therefore, a device operating at 60 watts on a 120-volt circuit would draw 0.5 amps of current.
A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
A 120 ohm resisto a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the current running through the 60 ohm resistor?
If they're in parallel, then each resistor acts as if it were the only one,and the presence of any others is irrelevant.The current through the 60-ohm resistor is I = E/R = (120/60) = 2 amperes.
What is the current in an AC circuit with a 120-volts and a 60 watt light bulb?
To calculate the current in the AC circuit, we can use the formula P = V * I, where P is power (60 watts), V is voltage (120 volts), and I is current. Rearranging the formula to solve for current I, we get I = P / V. Plugging in the values, I = 60 watts / 120 volts = 0.5 amps. Therefore, the current flowing through the circuit is 0.5 amps.
What is the purpose of a double pole 60 amp breaker in an electrical circuit?
A double pole 60 amp breaker in an electrical circuit is used to protect the circuit from overloading and short circuits by disconnecting power when the current exceeds 60 amps.
What is the current in an AC circuit with 120 volts and a 60-watt light bulb?
Power = (voltage) x (current) 60 = 120 x I I = 60/120 = 1/2 Amp.
What is the current in an ac circuit with 120-volts and a 60 -watt light bulb?
Current or amperage, is wattage divided by voltage. 60 / 120 = .5 amp.
