What will happen if you connect two unequal EMFS parallel?
When we connect two batteries with different emfs together in parallel they will act as a short circuit. But if there is a big difference in voltage there can be serious destruction, a large current may flow through the battery having lower voltage. It may overheat due the resistance inside and possibly explode.
Can you connect two ideal batteries EMF without internal resistance in parallel with a resistor?
When two ideal batteries of different voltages are connected together and the connection is also ideal, then Infinite current will flow from battery with higher voltage rating to the other. Connecting a resistor in parallel will not cause any change to this condition.
What happens when you connect a resistor to a battery?
The series resistance makes the circuit solvable. The resistor can’t get “both” 5V and 1V. It can get only one voltage. You have two batteries connected to the same two nodes trying to maintain a different potential difference between those nodes, but circuit analysis dictates each node can only have one potential.
When two unequal values of resistors are connected in parallel across a DC source greater current flows through the?
lower resistance
Since the current is inversely proportional to the resistance, more the value of resistance, less will be the current flowing through it. ∴ When two unequal values of resistors are connected in parallel across a dc source, greater current flows through the greater current flows through the lower resistance.
What happens when two points of unequal potential or voltage are connected?
When two voltage sources of different magnitude are connected in parallel then the charge from higher voltage source moves towards lower voltage source until and unless both voltage sources reach same potential.
Can you run 2 different batteries in parallel?
Connecting batteries of different voltage ratings in parallel is not possible. It will result in very large current flowing from battery of higher voltage rating to battery of lower voltage rating.
What happens when two batteries are connected in series?
Connecting batteries in series increases voltage, but does not increase overall amp-hour capacity. All batteries in a series bank must have the same amp-hour rating. Connecting batteries in parallel increases total current capacity by decreasing total resistance, and it also increases overall amp-hour capacity.
What is Loop rule?
The sum of the voltage differences across all of these circuit elements must be zero. This is known as Kirchhoff’s Loop Rule. Answer: Kirchhoff’s Loop Rule states that the sum of the voltage differences around the loop must be equal to zero. To find the sum, a direction of travel must be chosen.
Can a resistor be in series with a battery?
Resistors are in series whenever the flow of charge, or the current, must flow through components sequentially. Resistors connected in a series circuit: Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).
Why do resistors in parallel have less resistance?
Resistors in parallel In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference across them. The current through them will be different if they have different resistances.
