Question

An ideal voltage source is connected as shown in the figure.
What is the current flowing through the circuit?
(A) Zero
(B) Infinite
(C) 100 A
(D) None of these​

Answer 1

Answer:

the answer is (C) A is the right answer

Answer 2

The current flowing through the circuit in the given diagram will be - (B) Infinite

•Ohm's law states that "the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R)."

•Thus, V = IR.

•I = V/R.

•In the given diagram, R = 0.

•Dividing any number by zero will give infinity.

•Thus, I or current is infinite.

•This means all the current will flow in the wire.

•This will in turn, cause heating of wire.

•The condition stated above is called dead short or short circuit.
