What is the only thing that can use power in an electrical circuit?
The load that is connected to the circuit is what draws the power of the electrical circuit.
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
What are the three requirement for a complete circuit?
-- a power supply -- a load -- low-resistance material to connect the load to the power supply
What part of circuit is not necessary for the circuit to be complete?
By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.
What quantity is watt measured in?
A wattmeter is used to measure the power of a load.
What is the only thing that can use power in an electrical circuit?
The load that is connected to the circuit is what draws the power of the electrical circuit.
Why circuit breaker are connected in series with load?
Because it needs to be able to cut the power to the load. That's why circuit breakers are always the first piece of equipment in a circuit after the power supply.
What is the difference between amps and volt-amps?
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
A series circuit has 100mA flowing through a 1.5kohm load What is the power dissipated by the load?
A series circuit has 100mA flowing through a 1.5kohm load. The power dissipated by the load is equivalent to 15 Watt. This is based on the formula, power is equals to square current times load.
How does a circuit allow the electricity to flow?
A closed circuit with a power source and load.
How do you find open circuit voltage in circuit?
"Open circuit voltage" is a characteristic of a battery or power supply. You measure it exactly as the term suggests ... disconnect any load from it (or open the ON/OFF switch), and measure the voltage across the terminals of the battery or power supply while it's not supplying current to anything.
Can you measure power with a volt meter?
No. A voltmeter measures potential difference (voltage). To measure power, a wattmeter is required. On the other hand, for a d.c. circuit only, you could use a voltmeter and an ammeter, and multiply their readings in order to calculate the power of a load.
How do you find the power of a power?
You can find its open circuit voltage very easily with a meter, but that doesn't signify its power. For that you need to connect a suitable load (resistor) and measure the current delivered. Then power = volts x amps.
How do you do a simple circuit?
You require a power source, a conductor and a load.
Can you use electronic circuit as a load?
If you are just using the load to pull a small amount of current, then yes a electronic circuit can be used for that. If you want a resistive load to measure voltage drop or something similar, then no an electronic circuit will usually not work for that.
What is load in a circuit?
It's a power outputThis answer is incorrect.A 'load' is the name given to any device supplied by the circuit. For example, a motor could be a load, or a resistor, a lamp, etc.
What are the three requirement for a complete circuit?
-- a power supply -- a load -- low-resistance material to connect the load to the power supply
