∙ 2012-10-22 19:16:37Power 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.
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.
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.
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.

Amperes are a measure of current. Volts are a measure of electrical pressure (voltage) To convert one to the other you need to take the resistance to flow into account. current (in amperes) = voltage (in volts) / resistance (in ohms) voltage (in volts) = current (in amps) x resistance (in ohms)
Conductor losses or "I squared R losses" occur when electric current flows through a conductor. Conductor loss in watts equals the square of the current in amperes (I2) multiplied by the resistance of the conductor in ohms (R), and each watt of electrical energy is equal to 1 joule of heat.
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
3 amperes. Ohm's law: Voltage is ohms times amperes.
By Ohm's Law, resistance equals voltage divided by current; the resistance of a 12 volt electrical circuit having a current flow of 3 amperes is 4 ohms.
Amps, or amperes, are a measure of electrical current; ohms are a measure of electrical resistance. Both are widely used in physics.
