Why does a short circuit draw more current?

The simplest answer is because in a short circuit the resistance across it is zero. It can be explained very clearly by Ohm’s Law which is I=E/R. Assuming that the power source has a perfect voltage regulator which makes the E constant. So with a zero resistance the current becomes infinite.

Does a short circuit increase current flow?

A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source through the ‘short,’ and may even cause the power source to be destroyed.

What happens to current flow when you have a short circuit?

A short circuit implies that the two terminals are externally connected with resistance R=0 , the same as an ideal wire. This means there is zero voltage difference for any current value. This means that zero current can flow between the two terminals, regardless of any voltage difference.

How does the short circuit form what is its effect Brainly?

Short circuit occurs when naked live and neutral wires touch each other. In such situations, the resistance of the circuit becomes very less. As a result, the wires become hot and sparks are caused by Joule’s heating effect of current.

How does the short circuit form what is its effect short answer?

When a naked live wire and a neutral wires touches each other, a short circuit occurs. In situations like these, the resistance of the circuit becomes low. This results in the heating of the wires and it sparks due to Joule’s heating effect of current.

Why does a short circuit occur?

They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. In simpler terms, short circuits happen when hot wire touches a conductive object it’s not supposed to. The result of a short circuit can be appliance damage, electrical shock, or even a fire.
