In an electricalcircuit-- whether direct current (DC) or alternating current (AC) -- power is the product of thecurrentand voltage. Current, which is measured inamperes(A), is the rate at which the energy flows. Voltage, which is measured in volts (V), is the difference in charge betw...
What is a digital multimeter used for? A DMM is primarily used to verify one of the three factors of Ohm’s Law voltage (volts), current (amps) and resistance (ohms). This simple equation, expressed below, is commonly used by electrical engineers during diagnostic testing. V = I x R ...
This is measured in volts (V). The current is the available volume for the water to flow in. The larger the volume the more water can flow. This is measured in amperes (A). Resistance is volume reduction inside the pipe that restricts the flow of water. This is measured in ohms (R...

What should be the resistance to draw a current of 3.5 Amperes on 115 Volts? The current going through R6 is ___ A, and the voltage over R6 is ___ V. The current going through R45 is ___ A, and the voltage over R345 is ___ V. What is the voltage that can be applied ...
Corresponding to the drive current rating is the drain-source on-resistance (RDS(ON)) of a gate driver. While ideally the RDS(ON) value should be zero for a MOSFET when fully on, it is generally in the range of a few ohms due to its physical structure. This takes into account the...
ρ is the resistivity of the material in ohm metres, Ω⋅m E is the magnitude of the electric field in volts per metre, V⋅m^-1 J is the magnitude of the current density in amperes per square metre, A⋅m^-2 Many resistors and conductors have a uniform cross section with a uni...
