How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
What is resistance reading?
A measurement of opposition to electric current flow in a component or circuit.
What are applications of OHM METER?
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
How is total resistance calculated in a series circuit?
If the circuit consists of resistors only, you simply add the values of all the resistors, in ohms.
4 How do you determine current in a parallel DC circuit?
The current in each individual component of the parallel circuit is equal to (voltage across the combined group of parallel components) / (individual component's resistance). The total current is the sum of the individual currents. ============================== Another approach is to first calculate the combined effective resistance of the group of parallel components. -- take the reciprocal of each individual resistance -- add all the reciprocals -- the combined effective resistance is the reciprocal of the sum. Then, the total current through the parallel circuit is (voltage across the parallel circuit) / (combined effective resistance of the components).
Why could the total resistance of the circuit vary when measuring resistance using a multimeter?
Residence of one component varies overtime and from component to component.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
Will a circuit component with a high resistance will have a low electric current?
Yes

What does the ohm symbol mean?
The ohm symbol is used to represent resistance of a component or in a circuit
How do you find power in a series circuit?
Power dissipated by the entire series circuit = (voltage between its ends)2 / (sum of resistances of each component in the circuit). Power dissipated by one individual component in the series circuit = (current through the series circuit)2 x (resistance of the individual component).
What regulates the flow of electrons in an electrical circuit?
a. amperage and voltage b. the size and length of the wires c. voltage and resistance d. fuses and circuit breakers
How is total resistance calculated in a series circuit?
If the circuit consists of resistors only, you simply add the values of all the resistors, in ohms.
What blood vessel regulates systemic resistance?
which blood vessel regulates systemic resistance?
What are devises run by electrical energy represented as resistors in a circuit?
Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
What type of circuit measurement is made by placing a meters test leads in a parrallel with a deenergized component?
RESISTANCE
