The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
Electrical current is measured in amperes.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This can be expressed as the formula I V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
A measurement of electrical resistance. It is dimensionally equivalent to Volts / Amperes. (Voltage / Current)AnswerAn ohm is the unit of measurement of resistance. Resistance is not affected by either voltage or current, but by the length, cross-sectional area, and resistivity of the conductor.
Ohm's Law is commonly represented by the formula ( V = I \times R ), where ( V ) is the voltage (in volts), ( I ) is the current (in amperes), and ( R ) is the resistance (in ohms). The symbols represent the relationship between voltage, current, and resistance in an electrical circuit, indicating that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.
Power in a circuit is inversely proportional to the resistance, all other things being equal. Voltage equals amperes time resistances, so amperes equals voltage divided by resistance. Watts equals voltage times amperes, so watts equals voltage squared divided by resistance.
Resistance is an opposition to electrical currrent flow, which is more formally coulombs per second, or amperes. Voltage is electrical pressure, more formally joules per coulomb. When you multiply volts and amperes you get joules per second, or watts.

The "current" through any conductor is voltage across the conductor/conductor's resistance .The current is measured in "Amperes" (amps)."MA" stands for "Milliamps". There are 1,000 of those in one whole ampere.So, the current through a conductor is1,000 times the voltage across the conductor/conductor's resistance . . . in MA
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
Amperes measure the flow of electric current, indicating how much charge passes through a conductor in a given time. Volts measure the electrical potential difference or voltage, representing the force that pushes electric charges through a circuit. Ohms quantify electrical resistance, indicating how much a material opposes the flow of current. Together, these units are fundamental in understanding and calculating electrical circuits through Ohm's Law, which relates voltage, current, and resistance.
