What quantity is watt measured in?
A wattmeter is used to measure the power of a load.
What is the resistance of a 36watts ballast?
The resistance of a ballast can vary depending on its design and specific characteristics. To calculate the resistance of a 36-watt ballast, you would first need to know the voltage it operates at. Using Ohm's Law (R = V^2 / P), where R is resistance, V is voltage, and P is power, you can determine the resistance.
What is the SI unit and symbol for power?
The SI unit for power is the watt, symbolized as W.
What SI unit is used to express power?
the answer for the si unit of power is the watt or w
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
When connected to a 110-volt supply, the 60-watt 220-volt lamp will consume power that is calculated using the formula P = V^2 / R, where P is power, V is voltage, and R is resistance. Since the resistance of the lamp remains constant, the power consumption would be (110^2 / 220) = 55 watts. Thus, the lamp would consume 55 watts of power when connected across a 110-volt supply.
What is Power that is applied to an entire circuit consisting of resistance capacitance and inductance is called?
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
A power rating of 1 joule per s is known as?
A power rating of 1 joule per second is known as 1 watt.
Can you use a 270 watt in a 300 watt transformer?
If you mean how to use a resistance of so much power then it can be easily done through a step-down transformer which lowers the voltage supply and hence the power.
What are the formulas for Ohm's Law and Watt's Law?
Ohm's Law: V = I * R (Voltage = Current * Resistance) Watt's Law: P = V * I (Power = Voltage * Current)
How many ohms are in an watt?
They're are not related. Watts are measurement of power while Ohms are measurement of resistance. One watt equals one volt times one amp.
What is the power dissipated by a resistor with a current of 0.02 A and a resistance of 1000 ohms?
Power = I2 R = (0.02)2 x (1,000) = 0.4 watt
Is Watt Increase in series Connection Off Two Resistor?
No. The power (in watts) would decrease, due to the greater effective resistance.
Watts are measured in?
voltage is measured in ohms which is represented by the omega sign.
Which has a higher resistance a 5w lamp bulb or a 25w lamp bulb and how many times?
As per the formula for power (Power (Watt) = Voltage (V) x Current (i) & Resistance (R) = V / i), 25w lamp bulb would have higher resistance compared to that of 5w lamp bulb.
What does a light bulb have?
The resistance of a light bulb varies, depending on the type of bulb, the power rating, and the temperature. A typical incandescent 60 watt bulb, for instance has a cold resistance of about 30 ohms, and a hot resistance of about 240 ohms.
What is a word for unit of power?
A "watt" is a derived unit of power.
Is a 800 watt power amplifier can power a 1300 watt subwoofer?
yes/no
