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.
Why must an ohmmeter be connected to a disconnected circuit or component?
An ohmmeter must be connected to a disconnected circuit or component to ensure accurate resistance measurements. If the circuit is still connected, other components can influence the measurement, leading to erroneous readings. Additionally, applying a voltage from the ohmmeter in a live circuit could damage the meter or create hazardous conditions. Thus, isolating the component ensures that only the resistance of the component itself is measured.
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 component in an electrical circuit provides resistance?
The component in an electrical circuit that provides resistance is called a resistor.
How can a multimeter be used to measure the resistance of a circuit component?
A multimeter can be used to measure the resistance of a circuit component by setting it to the resistance measurement mode, connecting the probes to the component, and reading the resistance value displayed on the multimeter screen.
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 is resistance reading?
A measurement of opposition to electric current flow in a component or circuit.
Why does resistance increase in a series circuit?
In a series circuit, the total resistance increases because the individual resistances add up. As the current flows through each component in succession, the resistance offered by each component adds to the total resistance. This leads to an overall increase in resistance in a series circuit.

Thus, isolating the component ensures that only the resistance of the component itself is measured.
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 does the ohm symbol mean?
The ohm symbol is used to represent resistance of a component or in a circuit
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
