When lightbulbs are connected in a series how much current flows through each one?
same current flow in each bulb
Resistors connected in a single path is called?
The resistors connected in single path are called series resistances or resistances in series.The current across both the resistors is same while the potential differences are different.
How can the Murray loop test be used for locating the phase to phase fault?
By using wheatstone bridge principle we can proceed to find the phase to phase fault's.i:e the wheatstone bridge is mainly used to find the resistances/inductance/capacitances.it is mainly consists of 4 resistances like this(<>)& having a galvanometer in centre&a battery is connected to it. when ever the current flowing through the galvanometer is zero by varying the one resistance,then the ratio of two resistances connected at one end is equal to other two resistances ratio.By using the same principle ,one phase is connected to known resistance and a good cable is shorted to the fault cable.and other resistane is connected to the good cable&a galvanometer is connected to it.by varying the resistances the galvanometer shows null reading.then bridge is balanced & by using bridge equation we can solve to find the distance where the error is located
What happens to the brightness of the light bulbs in a series with a heater?
They dim as the total resistance of series of resistances is the sum of the resistances; and current = V/R.
How would you connect several resistances if you wish to increase the current?
Connect it in Parallel.
What are the series circuit rules?
current is constant in the series circuit. The resistances of the components add up and the potential differences is divided propotionally over the components depending on their resistances.
You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
What is the heating effect of resistances?
P=IE power(heat) = current * voltage or P=I*I*R
Modern electronic multimeter measures resistances by?
forcing a constant current and measuring the voltage across the unknown resistor.
Why is there less current in a circuit with four bulbs than there is in a circuit with one bulb?
yes because of bulb resistance :)
How do you calculate voltage's ampere's resistances in dc automobile systems?
Ohm's Law applies where Voltage = Current x Resistance
What is used to measure the current in a circuit and how is it connected?
To measure the current in the circuit an ammeter is used and it is connected in series
