6 FAQs about [Resistors as Batteries]
How does a resistor affect a battery?
Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where V = IR. Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit.
Will external resistor be ignored if a battery has a higher resistance?
A short answer anyway is that if external resistor is much higher than the internal resistance of batteries (i.e 0.1Ω), then ignored. @NickAlexeev no, it won't. Read carefully: the question is about parallel batteries, not series batteries: "positive to positive and negative to negative".
Can a circuit have more than one resistor?
Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected.
What is a resistor in current and resistance?
In Current and Resistance, we described the term ‘resistance’ and explained the basic design of a resistor. Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where V = IR. Most circuits have more than one resistor.
How many resistors does a 9 volt battery have?
A battery with a terminal voltage of 9 V is connected to a circuit consisting of four 20Ω and one 10Ω resistors all in series (Figure 10.3.3). Assume the battery has negligible internal resistance. Calculate the equivalent resistance of the circuit. Calculate the current through each resistor. Calculate the potential drop across each resistor.
What happens if you put a resistor across a power supply?
If the resistor was placed across the power supply alone, with a very low value, the high current draw could melt a fuse or create a short circuit, damaging the electric supply. It is possible to combine multiple cells together in a circuit to produce a battery. The properties of the battery depend on how the cells are connected together.
