What would happen to the bulb if we Gives supply from both sides?
Nothing will happen! There is no potential difference between the bulb’s leads, being at one and the same supply. So nthe bulb will not glow!
Will the bulb glow when 2 phase connected to it?
If phase to phase voltage is up to the thersold voltage of Lamp it will glow, A voltage greater than thersold voltage will damage the Lamp.
Why do you need two wires to make a light bulb work when connected to a power supply?
jack476 said: Now, the reason we need two wires is that to make those electrons move they need to use up potential energy. The positive terminal is high potential (has more potential energy) and the negative is low (or ground, which may or may not literally be the ground) potential.
Can a light have 2 power sources?
You can have power 1 or power 2 but not both at the same time and as was mentioned if the power sources are like US Residential split phase you need not worry about things getting ugly.
What will happen if one light bulb is removed from a parallel circuit?
Parallel circuits the rule is: The voltage stays the same and the current divides in each branch. When the one bulb is removed, it WILL NOT affect the other bulbs. The other bulbs will stay lit.
What happened to the other bulbs when one bulb was disconnected?
One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function.
What happens if we connect two phase wires?
If you connect two wires of the same phase, nothing would happen, except that the line can be treated as a double circuit line which would now have double the current carrying capacity. Also, when you want to short two lines of the same phase, make sure they are of the same voltage level and frequency.
What happens when two phases touch?
Thanks for the A2A. If two phase wires touch each other it is considered as a fault, the great Line to Line fault . This causes huge current to flow. If the circuit breaker is operative it will trip if it doesn’t there will be huge heat causing fire or melting of the wire.
Why do we need two wires?
Charge is not delivered from the supply to the load. Instead, charge moves around a circuit. That’s why you need two wires – for the charge to travel all the way around to form a current. Without a circuit the current can’t flow.
How do you wire two switches and lights using the same power source?
If you’ve mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail.
Is a two way switch?
In a two-way switch, there are two, one-way switches combined in one. One of the terminals can be connected to either of the two, but not both at the same time. The advantage of a two-way switch is the ability to control a single device from two separate locations.
