The technical definition is "Electrical resistance is a ratio of the degree to which an object opposes an electric current through it, measured in ohms." In simplfied terms, electrical resistance is broadly equivalent to friction in a mechanical system. If you applied a voltage to a circuit with zero resistance then you would get an infinite current. In reality all circuits have some resistance which limits the current. We can predict the current in a given circuit using Ohms law: V = I x R Where: V is Voltage (measured in Volts) I is current (measured in Amps) R is resistance (measured in Ohms)
What else can I help you with?
What term best describes an electrical circuit in which no current flows from the power source through the control component load and conductors?
A cold circuit
Why voltmeter should have a very high resistance?
well a voltmeter measures AC and DC voltage. resistance is a term used only for DC voltage, A voltmeter uses a term called Impedance for AC, without it, when you measure across two terminals it would create a short circuit and would blow up the meter. it is basically a safety feature to prevent people from creating short circuits when measuring.
what term describes the amount of charge that passes a point in a circuit each second Current Resistance Voltage power?
Current
What is reactance?
The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.
Define the electrical term VA?
'VA', or more correctly, V.A, is not an electrical 'term'. Rather, it is the symbol for 'volt ampere', the unit of measurement for a quantity called 'apparent power'. This is the product of the supply-voltage and load current for an a.c. load.
What is the term for the relationship of voltage current and resistance in simple electrical circuit?
Ohms Law
The ohm is the unit of measurement of quantity of positive electrical charges?
Ohm is a unit of measurement for resistance. The term ohm was named after a German physicist named Georg Simon Ohm.
What is the function of a build in an electric circuit?
I have never heard of an electrical term "build" in an electrical circuit.
What does resistance in an electrical circuit mean?
i dont know really, thats why im asking right
What is the difference between resistance box rheostat and resistor?
A resistance box is a device that contains a set of fixed resistors that can be connected in various combinations to achieve different resistance values. A rheostat is a variable resistor that can be adjusted to change the resistance in a circuit. A resistor is a general term for a component that resists the flow of electrical current in a circuit and comes in fixed resistance values.
What is the term used to designate the point in an electrical circuit where electrical work is done?
The term used to designate the point in an electrical circuit where electrical work is done is "load." The load is the component of the circuit that consumes electrical energy and converts it into another form of energy, such as light or heat.
What is the abstract noun for resist?
The abstract noun for the verb resist is the noun resistance (opposition, opposing force). As an electrical term, resistance is a property of the molecules of a substance, or their particular effect in a circuit.
What is the term for the the unit that measures electrical resistance?
ohm
How do you work out the current in a circuit?
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
What is a term for the relationship of voltage current and resistance in a simple electrical circuit?
Ohm's Law. According to Ohm's law V = iR where V is voltage (usually measured in volts) between two points of the circuit i is current (usually measured in amperes) between two points of the circuit R is resistance (usually measured in Ohms) between two points of the circuit.
What is the term amphere mean?
An ampere, typically abbreviated as "amp," is the unit of measurement for electrical current. It represents the rate at which electric charge flows in a circuit.
What term is often used to describe potential differences?
Voltage is the term often used to describe potential differences in electrical systems. It is measured in volts and represents the force or pressure that drives electric current through a circuit.
