What is the use of resistance box?
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
When they can use a resistor in a circuit?
When the circuit needs the electrical property of resistance, of course.
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
How to figure amps in an electrical circuit?
To figure out the amps in an electrical circuit, you can use Ohm's Law, which states that Amps Volts / Resistance. Measure the voltage across the circuit and the resistance of the components in the circuit, then divide the voltage by the resistance to calculate the amperage.
Examples of electrical resistance?
The filament in an incandescent light bulb resists the flow of electricity. Copper wire has relatively low electrical resistance, making it a common choice for transmitting electricity. Insulators, such as rubber or plastic, have high electrical resistance, which prevents the flow of electricity.
Who when and how was electrical resistance discovered?
electrical resistance was discovered by Georg Ohm in the late 1820's.
What are the units of resistance in an electrical circuit measured in?
The units of resistance in an electrical circuit are measured in ohms ().
Is copper low or high resistance?
Copper is known for its low electrical resistance, making it a highly conductive material. This property of copper makes it ideal for use in electrical wiring and other applications where efficient electrical conductivity is required.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What are some ways a material's electrical resistance is used to accomplish a certain job?
A good example of electrical resistance is the heating element on a stove top it is a very poor conductor (high electrical resistance) because it is a poor conductor the electrical energy is converted to heat. Glass is one of the best insulators because its electrical resistance is so high it is a non conductor this lets us use it on high power lines to keep the electricity from coming in contact with the ground.
What component in an electrical circuit provides resistance?
The component in an electrical circuit that provides resistance is called a resistor.
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
