0.3 amps

In a given circuit, the supplied voltage is 1.5 volts and the resistor value is 3 ohms. Use ohms law to determine the current of the circuit.

0.5 amps

A series circuit contains a 9-volt battery, a 3-ohm resistor, and a 2-ohm resistor. What is the voltage drop across the 2-ohm resistor?

3.6 V

parallel circuit

A circuit with two or more loops through which the current can flow

series circuit

An electric current in which resistors are arranged so that they come one after another

Ampere

The unit for measuring the strength

Which factors determine the amount of electric current in a circuit

Voltage, resistance

According to Ohms law, a circuit with a high resistance:

Will have a low electric current

fuse

a circuit element that contains a wire that melts when the current gets too high, this creating an open circuit

Ammeter

a device used to measure current

Resistance

a measure of how well electric current flows through a material

open circuit

an incomplete electrical circuit in which no current flows due to an open switch or fuse

In a parallel circuit, each resistor has:

its own connection to the voltage source

Which of the following would not be a good fuse design?

low-melt wire encased in iron

A break in the wires of an electric current will ___ the circuit and ___ the current. Reconnecting the wires will ___ the circuit and ___ the current.

open, stop, close, start

The purpose of a fuse or circuit breaker is ___.

to stop current that is flowing too fast
