Amps = 3000W/150V = 20 A What Is a Volt? A volt measures the electrical potential difference or electromotive force. It measures how much energy each charging unit carries when moving between two points in a system. Mathematically, you can use this equation to calculate volts if you know ...
Current (I) is a rate of flow and is measured in amps (A). Ohms (R) is a measure of resistance and is analogous to the water pipe size. Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure. Voltage is an expression of the available e...
A current of 2 amps is flowing through a 3 ohm resistor. How much power is dissipated by the resistor?The electric power of a lamp that carries 2 amps at 120 volts is: A. 1/6 watts B. 60 watts C. 20 watts D. 2 watts E. 240 wattsHow many amperes flow through a 60 watt bulb...
If a voltmeter is connected between the terminals of a resistor, what will it read when the current in that 8.0 Ohms resistor is 3.60 A ? R1= 24.8 ohms R2= 13.9 ohms R3= 25.5 ohms V1= 5 volts V2= 11.9 volts V3= 9.1 vol...
Convert volts/amps to watts.If your appliance’s power requirements are in volts or amps, you can calculate an appliance’s running watts with this equation: Volts (V) x Amps (A) = Watts (W) Count the running watts of your appliances.Add up the running watts of the appliances ...
That is, volts = amps x ohms. If resistance is unknown, the formula can be converted to R = E/I (ohms = volts / amps). Examples of Circuit Resistance Normal Circuit Resistance In an electric heater circuit, as portrayed in the two illustrations below, resistance is determined by ...
The accepted ampere hour rating time period forsolarelectric batteries, deep-cycle batteries and backup power systems --uninterruptable power supplies-- is generally a 20-hour rate. The rating indicates that the battery is discharged to 10.5 volts over 20 hours, while the total ampere hours supp...
W = power in watts V = potential in volts I = current in amps Q = charge in coulombs t = time in seconds What is a watt: unit of power The unit of power is the watt which is denoted by the symbol W and it is named after the Scottish engineer James Watt (1736–1819). ...
