In Ohm's Law, E stands for voltage, I stands for current (amps), and R stands for resistance. Ohm's Law states: E = IR or voltage equals current times resistance. This means that current flowing through a wire (that has resistance) produces a voltage drop in the wire. Since the voltage drop is the result of current flowing through a resistance, old-school engineers will sometimes refer to it as "IR drop". So, since E = IR, saying "IR" is the same as saying "voltage".
What else can I help you with?
If a toy car with a resistance of 2 ohms is connected to a 3v battery how much current flows through the car?
Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).
What does voltage current mean?
V=IR, voltage is directly propostional to current and resistance (by ohm's law).CommentVoltage is not 'proportional to resistance'. Resistance is a constant, and is not affected by voltage at all.
How micro ohm meter work in detail?
A current is passed through a resistor and the voltage drop is measured on the other side. It follows Ohm's law by a given current and voltage you can measure the resistance of a resistor by V=IR.
The mathematical relationship between current voltage and resistance is known as?
Ohm's LawAnswerIt's not known as anything; it's simply an equation. Ohm's Law describes constant proportionality between current and voltage for certain, but not all, materials (linear or ohmic) -it has nothing to do with this equation.
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is the formula for voltage sensitivity?
V=ir

What is IR drop?
IR Drop means voltage drop. As voltage drop across any resistance is product of current (I) passing through resistance and resistance value(R ) , it is often written as IR drop.
What is the English meaning of ir?
Ir means "to go"
Electricians have another term for voltage drop in a cable What is it?
the formular notation for voltage drop is Ed Another possible term is "IR loss" meaning the current (I) x resistance (R) loss on the wire part of a circuit
What is a IR drop across a resistance?
IR drop across a resistance is voltage. The letter I means current, and the letter R means resistance. Current times resistance, by Ohm's law is voltage.
How do you calculate resistance?
You need to use the formula E = IR + Ir where: E is the e.m.f. of the power supply (the theoretical maximum voltage across the terminals when no current is flowing) I is current R is resistance of the circuit (load resistance) and r is the internal resistance of the power supply. Therefore, you can rearrange this formula to give r: E = IR + Ir (Subtract IR) E-IR=Ir (divide by I) (E-IR)/I=r or r=(E-IR)/I
If you add the IR drop or voltage drop of each individual resistance in a series circuit is it equal to the applied voltage?
Yes
What is the symbol for voltage in ohm's law?
Voltage = Current x Resistance is often written V = I x R. Ohm's Law is: E = IR E is voltage
What changes with the electric current?
Since V=IR then the answer would be voltage and/or resistance.AnswerIn the equation, V = IR, resistance is a constant -so it does not change with a change in current.
What does voltage current mean?

What is the relation between voltage and ampere of any intument?
V=IR where V is the voltage (volts), I is current (amps) and R is resistance (ohms)
