What size wire for a 230 volt circuit?
The size of the wire is set by the maximum current it has to carry. The voltage sets the size of the insulation. In the UK a 230 v (nominal) ring-circuit supplying a set of power sockets is rated at 30 amps and uses a ring of 2.5 sq-mm cable.
What are three sources of power for control circuit?
The Three sources of power for control circuit are dynamic power, short-circuit power and leakage power.
If you are using a multimeter as an ohmmeter and you get a reading of maximum resistance what does that tell you about the circuit you are measuring?
Did you mean "maximum RESISTANCE" or "maximum VALUE"? If the former, then, you have a ZERO reading, meaning there is high resistance, and no electrical connectivity. If the latter, you have a ONE (or 100%) reading, meaning there is NO resistance, or absolute electrical connectivity. As an analogy, if you turn on a plugged-in, working, lamp, then it has NO resistance, such that power flows easily through the cord; if it didn't turn on, then there IS resistance, such that no power flows, possibly due to broken wire, bad switch, burned-out bulb, or blown fuse.
A small appliance circuit will be protected by a circuit breaker rated at?
Yes, it will be protected by a circuit breaker or fuse. The normal rating of the circuit breaker or fuse is 25% more than the maximum current expected, or the maximum current allowed for the cable size, whichever is lower.
How much amps in a 3 v circuit?
This cannot be answered without knowing what size load you are connecting to the circuit. In the absence of a load, with a dead short, you will get a flow of amps at the maximum that the power supply can provide. I have no way of knowing what that is.
Why is there no power in the socket for the trailer lights?
Are you getting power to sockets? Make sure you have a good ground circuit
In which circuit will the light bulb be the brightest?
the circuit which has the maximum power output
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
What size wire for a 230 volt circuit?
The size of the wire is set by the maximum current it has to carry. The voltage sets the size of the insulation. In the UK a 230 v (nominal) ring-circuit supplying a set of power sockets is rated at 30 amps and uses a ring of 2.5 sq-mm cable.
How maximum output power obtained?
when all the resistance removed from the circuit
When a source is delivering maximum power to load the efficiency of the circuit is always?
50%
What is maximum power of a 59ma power and 8.2kohm resistor circuit?
P=I2R=(59mA)2(8.2kohms)= 28.5443W
What is Doubling Effect in power system?
It is define as twice the maximum symetrical short circuit current.
Condition of resonance in RLC circuit?
XL=Xc is the resonance condition for an RLC circuit
How many sockets can their be in a power adapter?
I have seen power adapters that have at least 10 sockets. That will give you plenty of room for space!
What will happen in case of AC circuit for maximum power transfer theorem?
According to maximum power transfer theorem for ac circuits maximum power is transferred from source to load when the load resistance is equal to the magnitude of source impedance. The source imoedance is the thevenin equivalent impedance across the load
What is electrical domestic circuit?
Answer for UK, Europe and countries running a 50 Hz supply service.It is a set of power cables carrying electric power round domestic premises.In the UK you might have a lighting circuit for the lights, a ring circuit for power sockets and a cooker circuit to supply the cooker. Typical ratings are 10 A for lights and 30 A for power and cooker circuits. Extra curcuits might be added for space-heating and a shower.Each of these circuits is separately fused to that if there is a fault leading to a blown fuse, not all the power disappears.
