What will happen in a circuit if the intermediate switch is replace by a double pole switch?

The circuit will not work. The intermediate switch has to be a cross over switch. Visualise and draw on a piece of paper a rectangular box. Label the switch terminals as top left A , top right B, bottom left C and bottom right D. In one position of the toggle handle the terminals A - B are connected. In the same handle position C -D are connected. In the other handle position A - D are connected. In the same handle position C - B are connected. A double pole switch will just open both lines and the circuit stops working.
The answer following this answer is not referring to an intermeadiate switch but
replacing a single pole (SP) switch with a double pole (DP) switch.

Replacing a single pole (SP) switch with a double pole (DP) switch would be ok as long as it's rated as good or higher than the switch it's replacing, and as long as it fits.
It may weigh more than a SP switch as a DP switch would be slightly larger and have more contacts.
If replacing a SP switch with a DP switch, using one with the Off position in the middle may cause confusion.
If replacing a SP switch with a DP switch on a circuit board it may not fit if the board is crowded. You may also have to clip off the unused lead(s) as there may not be any provision (thru hole(s)) on the board for them (or it).

What is the object called that uses electricity in a circuit to make something happen?
The object that uses electricity in a circuit to make something happen is known as the load. Usually the load is rated in watts.
What will happen to the charges in a circuit a when a switch is closed?
the electrons are not allowed to enter into the circuit.
What happen when felsic magma mix with basic magma?
Felsic and mafic (basic) magam mix to form intermediate magma.
An appliance does not work at all when plug it in and turn the switch what happen to the appliance circuit is?
If an appliance does not work at all when you plug it in and turn the switch on the appliance circuit is not on.
Why fuse wire is placed in series with the device?
circuit breaker and fuses used in series to break the circuit in overcurrent situation to block current to flow through circuit.
What happen to current in a circuit if the voltage in not charged but the resistant is double?
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.

Circuit's Edge happened in 1990.
When you will get to know that short circuit will happen?
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
What will happen if you replace a 10 amp fuse with a 15 amp fuse?
You risk too much current flow in the circuit. Overloading the wiring can cause a fire.
What will happen to the circuit if the bulb if removed from its holder?
Nothing will happen to circuit..... as usual the circuit would be supplying 220v(if india) and certain current...but there is no bulb to consume power...
What happen when there is a break in the path circuit?
Current through that part of the circuit will stop.
What will happen to the transformer if double the rated voltage is applied to the winding during the open circuit test?
no voltage will be induced on the secondary side of the motor as the windings will become saturated.
What would happen if a lamp was unscrewed from a parallel circuit?
There will be no change, because it is a parallel circuit.
What does a short circuit happen?
when the fuse is not working
What happen to the circuit if there is higher resistance?
In what sense.
