In its simplest use a resistor in a circuit is used to limit the amount of current flow, or to decrease the amount of voltage applied to a device. One example is you had a 12 volt battery and you need/ wanted to connect it to a device that ran on 9 volts then a resistor can be chosen to reduce the 12 volts to the 9 volts required.
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.
No. It will not serve its intended purpose.
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
They use transistor as the purpose to transfer the voltage

The TBA820 is a 2 watt general purpose amplifier integrated circuit, not a resistor.

It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
To avoid shocks and to avoid damage to the electronic gadgets
In a bridge circuit the unknown resistor is compared to the rheostat. When the meter across the bridge reads in the middle the unknown and the rheostat are the same value.
Resistors are used in various daily life applications such as in household appliances to control the flow of current, in electronic devices to limit current and voltage, and in heating elements to regulate temperature. They are also used in LEDs to protect them from too much current and in audio systems to adjust volume levels.
To pass current very easily from one part of a circuit to another.
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
A variable resistor is used in cicuits to vary the current passing through the resistor. It is commonly used to change the value of current across a circuit, or to act as a voltage divider. They are commonly equiped with a knob outside of a cabinet, to enable the user to adjust the operation of a circuit, like a volume control on a radio or amplifier.
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
