One thousand watts of electric power are transmitted to a device by means of two wires, each of which has a resistance of 2 ohms. If the resulting potential difference across the device is 100 volts, the potential difference across the source supplying the power is: A. 20 V B. 40 V C. 100 V D. 140 V E. 500 V

All electrical appliances are rated in watts (W) or kilowatts (kW) ( One kilowatt is the same as 1,000 watts). You can use the ratings to compare how much electricity they use. Electricity used at home is metered in 'units' or kilowatt hours (kWh). Each unit is the same as 1,000 watts of electricity used for 1 hour. 1 unit = 1kWh.

What is the PD across the source if 1,000 watts of electric power is transmitted to a device by means of two wires, each of which has a resistance of 2 ohms and the resulting potential difference across the device is 100 volts?

voltage = 10,000 volts. power = 100,000 watts. So. current = 100,000 W 10,000 V = 10 A. Now. power loss = I 2 ×R [current squared ×resistance] So. power loss = (10 A)2 × 5 Ω = 500 W. Answer link.

Transmitting electricity at high voltage reduces the fraction of energy lost to resistance, which varies depending on the specific conductors, the current flowing, and the length of the transmission line. For example, a 100 mi (160 km) span at 765 kV carrying 1000 MW of power can have losses of 1.1% to 0.5%.

The basic unit of measure of electric power is the watt. One thousand watts are called a kilowatt. If you use one thousand watts of power in one hour, you have used one kilowatt-hour (kWh). Your electric utility bills you by the kWh. Natural gas is commonly measured by the cubic foot, and you are billed by the thousands of cubic feet (MCF) or the

Electricity is transmitted at high voltages up to 1.2MV (1200 kilo Volts) in some countries. Source & Credit: GE Reports Electricity transmitted at high voltages Electric power transmission network should be efficient, safe and at the same time economical.

Amps x Volts = Watts (Amps times Volts = Watts) Maximum vs. Rated Power. Generators are often advertised at the maximum wattage they can produce. But you’ll also see the “rated power” listed. Maximum power = the maximum output that a generator can produce. Maximum power is usually available for up to 30 minutes.

Wh = 1 Calorie (approximately) 1kWh = 1000 Calories Joule. Physicists like to the use energy unit called the joule (named after James Joule) because it makes their equations look simpler. There are about 4000 joules in a Calorie, 3600 in a Wh, 3.6 million in a kWh. The energy table below shows the approximate energies in various substances.

Accordingly, to the army inspiration, this bike has an integrated motor of 1000 Watt power. It is a mid driven electric motor with high torque. It is strategically placed on the next to the pedals so that it can sense the speed you are pedaling with and start the assisting mode when you need an additional boost.
