As current is the rate of flow of electric charges
so,there must be free electrons for the flow of electric current in a circuit.Then when voltage is applied at the terminals of circuit the free electrons acquire an average velocity called as drift velocity in the opposite direction to that of electric field (-E).Now the free electrons modify there random motion and a steady current begin to flow in a circuit.
True
In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.When the two branches have the same resistance, the same current flows through each branch.When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!Hope i helped ;)
A cold circuit
3 Ampere
This is the current flowing in the primary circuit when full-load current flows in the secondary circuit.
Current flows through a complete circuit.
True
A circuit breaker is a device used to open a circuit if too much current flows through it.
DC = direct current.
An electrical current.
"circuit"
complex circuit
True
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Yes. Current consists of electrons flowing in a circuit.
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
This would not be a hypothesis, but an explanation. A fuse is a piece of wire with a low melting point which melts if too much current flows in the circuit. It is designed to break before the rest of the circuit is damaged.
