In a parallel circuit, Voltage is constant through out the circuit. Thus, the voltage across each lamp is 6-volts.
Assuming there are no other circuit elements, such as resistances, then (by Kirchoff's Laws) the voltage across the bulb will also be 6 volts.
For a series circuit: 3V. For a parallel circuit: 6V.
Two.
Torch equals flashlight. Battery negative connected to case switched to bulbs outside. Positive connected to the lamps bottom. Called a series circuit.
In North America the neutral wire is never fused. This is because of the three wire circuit that uses a common neutral. If there are two loads connected across a common neutral circuit and the neutral opens a 230 volt supply will be impressed across both loads as they are now in series with the supply. If both loads were balanced then the voltage drop across both loads would be equal. Dropping 120 volts across each load. Where the problem arises is if the two loads are not balanced and voltage drop goes higher than the manufactures recommended voltage, then the connected device could burn out.
If the voltage and resistance values remain the same the power dissipated will be 90 W.
series connected
With some difficulty. Easiest way would be with three lights connected in series, shining at the same time.
If all four lamps are identical, there will be an identical voltage drop on each. 3 volts / 4 lamps = 0.75 voltage drop at each light.
The potential difference across two resistors connected in parallel to a battery with a potential difference of 6 volts is 6 volts. Kirchoff's Voltage Law: The signed sum of the voltage drops in a series circuit is zero. This means that that the two series circuits involving the battery and each resistor have the same voltage across each other, and the series circuit involving the two resistors have the same voltage across each other.
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
v of what? v across what? v measured from what 2 points? v across the coils? v across the resistor? v across the coils and resistor? v across the battery? v across the battery and coils? v across the battery and resistor? or are you asking what v stands for? v stands for voltage.
Series.
Two toy electric trains running on the same track are connected in parallel because they both get energized from DC impressed across the two rails they ride on.
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.
Measures the amperage of the current .Your battery is in series with your car amp meter .
There is a 3.75 Volt drop across each bulb.
The voltmeter is connected across the supply and the ammeter is connected in series with the supply.
Battery cells are conneted in series. Each cell of a 12v battery averages 2.1v when charged. SERIES 2-4-6-8 and so on
When the batteries are connected in parralell, the voltage remains the same as a single battery, but the current capability is doubled. When connected in series, the voltage doubles at the light, but the current remains the same as if a single battery was connected. Ohm's Law E=IxR R=E divided by I I=E divided by R E=Voltage R=Resistance I=Current
