#### exists and is an alternate of .

When too much current flows through the fuse, it heats up and melts. Hence, the circuit is broken and the current does not flow through the circuit or the gadget.

# Do volts measure the flow of an electric current through a circuit?

No, voltage is not the measure of the flow of electric current through a circuit. Voltage is the difference in potential of the source.

# What opens a circuit by melting when too much electricity flows through a circuit?

A good old fuse .

# How a fuse controls the flow of electric current in a circuit?

A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the

# What happens when too much electrical current passes through the metal strip on a fuse?

It will burn out.

# An electric current can only flow through a circuit that is?

"closed" "complete" (loop)

# Why does the filament bulb not light up when there is too much current flowing through the circuit?

The most likely reason is that the over current has burned the bulb filament open.

false

# Too much current flowing in a circuit?

When too much current passes through a conductor it can cause an overload of electricity which if not earthed can be very dangerous to human contact. If the object that is con

# What does a fuse or circuit breaker do when too much electricity flows through a circuit?

A fuse or circuit breakers purpose in a circuit is to disconnect the circuit load from the voltage source when a circuit fault occurs.

# What determines the amount of electric current flow through a circuit?

voltage and resistance v=ir v=voltage i=current r=resistance in physics right now

# What causes a current to flow through an electric circuit?

A voltage. That acts like a force on electrons (or other charged particles), pushing them away from one end, and attracting them to the other end (of a battery, for example).\

# How could you prevent too much current from flowing through a wire?

by resistor installation

# What will happen to a fuse if too much current flows?

It will "open". this will stop current flow. Most folks say you have a blown fuse or the fuse blew (blue?) which is actually incorrect.

# Is electric current flows only through a closed circuit?

Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current. Answer An interesting question. The answer is.... not nece
