You can measure across *any* component - see the answer on measuring voltage.
For any resistance measurement, be SURE that:
1. The circuit is disconnected from the power supply, and
2. "Energy storage" components such as capacitors are discharged.
If the circuit does contain capacitors of reasonable size (microfarads or more) these may demand some power from the meter to charge them, so you can get an artificially low reading at first, but it will rise to the correct value as the capacitors charge.
What else can I help you with?
In a parallel circuit does the battery run out very quickly?
No, it will run out just as much as if you put it in a series circuit. Parallel circuits involve the same voltage or amperage to go to each component.
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
Compare and contrast series and parallel circuits?
In a series circuit, there is only one path for the current to flow through. In a parallel circuit, there are multiple paths for the current to flow through. For example, most old Christmas lights are series circuits. If one light in the whole strand of lights went out, then all the lights would go out. This is because once one resistance is out, the circuit is no longer complete, so the current can not flow. An example of a parallel circuit could be your household lighting. When you turn on your kitchen lights, your bathroom lights don't turn on with it, do they? That is because it is a parallel circuit. In a parallel circuit, there are multiple paths for the current. It doesn't matter if one light is on and another is off because the current can go through another way. In a series circuit as you increase resistance, the voltage and current decrease. In a parallel circuit, as you increase resistance, the voltage and current increase. Think of a series circuit as a one-lane road. The car would be the current, the gas in the car would the voltage, and the traffic lights would be the resistance. Since you are on a one-lane road, as you keep stopping at traffic lights, you aren't going very fast or far. Now, think of parallel circuits as a multi-lane road (or highway). The car is the current, the gas in the car is the voltage, and the traffic lights (or closed roads, or accidents, anything that would slow you down on the road) are the resistance. When you are driving and one road is closed, you don't have to stop because you can continue driving and go on a different road to reach your destination.
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
How much voltage does each branch of a parallel circuit?
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
What is the same in each branch of a parallel circuit?
In a parallel circuit, the voltage across each branch is the same.
Is voltage the same in parallel circuits?
No, voltage is not the same in parallel circuits. Voltage is constant across components in a series circuit, but in a parallel circuit, each component has the same voltage as the power source.
Why a voltage only in parallel?
Depends on what circuit you're refering to, a parallel circuit has parallel lines because it allows for voltage to pass through the circuit, giving more power.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
What happens in a parallel circuit when one battery is added?
When a battery is added to a parallel circuit, the total voltage in the circuit increases as the new battery adds its voltage to the existing voltage sources. The total current in the circuit may also increase as the additional voltage motivates the charges to flow through the parallel branches of the circuit.
In a parallel circuit the is the same for every leg in the circuit?
voltage
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
What is same in the parallel circuit?
the term voltage is constant in parallel circuits
In which circuit is the voltage the same across all branches?
Parallel circuit.
