What else can I help you with?
What are the uses of the relay?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
What is he definition of electrical current?
The current flowing in an electrical circuit.
What is a circuit called if its operating and the current is flowing?
A closed circuit is one where the current is flowing continuously from the source to the load and back to the source, completing a loop. An open circuit, on the other hand, is one where the current cannot flow because the circuit is broken at some point.
What can be used to test if electricity is flowing in a circuit?
A Galvanometer can be used to detect the presence of current in a circuit. An ammeter can be used to know the magnitude of the current flowing through the circuit.
How do resistors affect the change in current flowing through a circuit?
Resistors in a circuit reduce the flow of current by impeding the movement of electrons. This causes a decrease in the overall current flowing through the circuit.
What is the current flowing in a circuit measured in?
amperes or A.
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
What does the am meter do in a circuit?
An ammeter measures the amount of current flowing in a circuit
In an electric circuit the ground prevents current from flowing in the circuit.?
false
When is the current flowing in a circuit said to be very small?
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
Which instrument would be used to measure current flowing in a circuit?
A multimeter set to measure current (in amperes) would be used to measure current flowing in a circuit. The multimeter needs to be connected in series with the circuit to accurately measure the current.
What kind of force keeps current flowing in a circuit?
Electric potential difference or voltage is the force that keeps current flowing in a circuit. The potential difference creates an electric field, which in turn exerts a force on the charged particles in the circuit, causing them to move and establish a current flow.
