What is the relationship between the current leaving the source and the current through each load in a series circuit?
A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.
How could you calculate the resistance of a circuit?
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
Why is a fuse wire necessary in a circuit?
a fuse wire melts when current passing through it exceeds a certain value as in overloading and short circuiting .this breaks the circuit prventing further current flow and damage ..
What is DTOC relay?
A definite time over-current relay operates like an instantaneous over-current relay coupled with a timer. Once current reaches the pick-up value, it initiates the timing circuit. As long as current stays above this pick-up value, the timer will continue to time. Once the definite time setting is reached, the relay gives trip signal to the circuit breaker.
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
What is the average value of the alternating current (AC) in the circuit?
The average value of the alternating current (AC) in the circuit is calculated by finding the root mean square (RMS) value of the current waveform. This value represents the equivalent direct current that would produce the same amount of power dissipation in a resistor as the AC current.
What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
What a device that protects an electric circuit from too much current?
Circuit Breakers and Fuses limit the amount of current flowing through the circuit.
What is the rated short circuit capacity of the miniature circuit breaker used?
Breaking Current: The r.m.s value of short circuit current at the instant of contact separation.
What are the functions of a consumer?

What is design current?
BS7671:2008, Requirements for Electrical Installations, defines the design current (of a circuit) as 'the magnitude of the current (rms value for a.c.) to be carried by the circuit in normal service'.
What are current relays?
Current relays are the relay which sens the current passing in particular circuit and operates when this current exceed its set value.
What happens to current in a parallel circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.
What are the function of consumer box?

What devices are used to deliberately create an open circuit when the current exceeds a specific value?
fuses or circuit breakers
