In a circuit the voltage across all resistores is the same?
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
What will be the resultant voltage across different voltage points connected in parallel?
The voltages appearing across each branch of a parallel circuit will be equal to the supply voltage.
When the voltmeter is connected across the open in the circuit the meter will indicate a voltage equal to the?
The source voltage.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
How are circuits connected when you are using more than one battery?
The batteries can be connected in parallel or in series. In parallel, good batteries of the same voltage will have a total voltage across them equal to the voltage across one of them. Those batteries in series will have a total voltage equal to the sum of the voltage of each of the batteries.
Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
What is the different between using the low or high voltage in big three phase motors?
These types of motors are classified as dual voltage motors. The highest motor voltage rating is always double the lowest voltage rating. Dual voltage motors are more versatile in matching the system voltage supply that they are connected to. When the motor uses the highest voltage rating the coil legs are in series, dropping the high voltage across two coils. When the motor is connected to the low voltage rating the coils are connected in parallel dropping the low voltage rating across the two coils in parallel. As you can see no matter which configuration that you use the individual coils can never get a voltage across them greater than the lowest of the two voltages available. The connection diagram is usually on the underside of the motor's junction box lid.
What is the reason for bulb becoming dim when connected in series?
the voltage across it is reduced, the voltage is shared with other bulbs
How you calculate the polarity of voltage source across the resistor when two voltage sources are connected?
A: by using thevenin theorem
To measure voltage drop across a component or connector the voltmeter must be connected in?
it must be connected in parallel as always
Connected in series or parallel will each bulb glow brighter?
In parallel, each bulb will have full voltage applied across them. However, in series, the voltage across each bulb won't be the same as supply voltage. Thereby, bulbs connected in parallel will glow brighter.
