Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.

Why must voltmeter be connected in parallel with the circuit component?
Because, by definition, a voltage is the difference in potential between two different points. So the voltmeter must be connected across those points in order to measure that voltage -i.e. in parallel with the points.B
Give the characteristics of a parallel circuit?
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
Parallel operation of transformers?
Transformers can be connected in parallel, if they have the same primary and secondary voltages and equal operating frequency.
What is formula for connecting 2 capacitors in parallel?
The result of connecting two capacitors in parallel is a new capacitor whose capacitance is the sum of the values of the two you connected up. Note. the safe working voltage is equal to the lower of the two working voltages on the two capacitors.
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.
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.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
What happens to voltages and currents when there are passive elements connected in series and in parallel?
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.
Three equal resistors connected in series across a voltage source dissipate a power of 10W what sould be the power desipated if same resistors are connected in parallel?
If the voltage and resistance values remain the same the power dissipated will be 90 W.
Why is The voltage across the empty socket is equal to the line voltage?
all the sockets are always connected in parallel,due to this the voltage across each soket is same. when any socket is open then there is no voltage loss..so the votage is same like line voltage.
Why must voltmeter be connected in parallel with the circuit component?
Because, by definition, a voltage is the difference in potential between two different points. So the voltmeter must be connected across those points in order to measure that voltage -i.e. in parallel with the points.B
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
Give the characteristics of a parallel circuit?
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
If diode is connected to two voltage sourceone in forward biased other biased diode in rewrse what will be net effect of two source on diode?
If a diode is connected with two voltage sources for ex: One is 5V in F.B and The other is 3V in R.B then the Effective voltage will be equal to 2V F.B. So, The diode conducts.
When the voltmeter is connected across the open in the circuit the meter will indicate a voltage equal to the?
The source voltage.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
