A resistor is one of the most common elements of any circuit. Resistors are used:
1. to reduce the value of current in the circuit;
2. to produce IR voltage drop and in this way to change the value of the voltage.
When current is passing through a resistor its temperature rises high. The higher the value of current the higher is the temperature of a resistor. Each resistor has a maximum temperature to which it may be heated without a trouble. If the temperature rises higher the resistor gets open and opens the circuit.
Resistors are rated in watts. The watt is the rate at which electric energy is supplied when a current of one ampere is passing at a potential difference of one volt.

Modern telegraph systems are based upon the fact that electric current will flow through a wire which forms a circuit. The circuit can be broken to interrupt the flow of electricity and closed again for a short time by a key to send an electrical impulse through the circuit. When the key is pressed the circuit is closed. Electricity from the battery flows through the wire and earth circuit and causes the buzzer to make a noise. Using the Morse code, or some other code, messages can be sent in this way.
Ancient telegraph systems are based upon the fact that electrons flows through a drum.
The circuit can be interrupted the flow of water.
The circuit can be closed for a short time by a coil.
Electrical impulses will not flow through a wire if the circuit is broken.

Why are solar cells chosen to provide power for most space installations?
Since solar cells are able to utilize artificial light, they are the best choice as a power source for space installations.
Solar cells are chosen to provide power for most space installations, because they are the safest way to produce energy.
Solar cells provide power for most space installations because other electric power sources are prohibitively expensive to install.
Solar cells provide power for most space installations because they have no moving parts that need service or fuels that require refilling.
