What is the relationship between voltage and current and resistance in a simple circuit?
The simplest way to understand it is to use Ohm's law: E = IR. Voltage (E) can be though of as pressure that drives the current. Voltage is measured in volts. Current (I) can be thought of as the actual flow of electrons within the circuit. Current is measured in amperes, or amps. Resistance (R) can be thought of as exactly that - the amount of opposition to current flow in a circuit or component. Resistance is measured in ohms. So let's see how this works. E = IR. If E is constant (typical for a battery) then the current (I) is equal to the voltage divided by the resistance. Let's use a voltage of 12 volts, and a resistance of 2 ohms. The current is I = 12 volts/2 ohms= 6 amps. If you remember Ohms law, you can predict what will happen in simple circuits using only a little bit of simple algebra. What is arguably the simplest form of this relationship is that a 1 volt source connected to a 1 ohm resistor will cause 1 amp of current to flow. There are other ways to say the same thing. A 1 ohm resistor with 1 amp of current flowing through it must be connected to a 1 volt source. A 1 volt source that causes 1 amp of current flow must be connected to a 1 ohm resistance.

What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
What relationship does Ohm's law express?

What happens to the current in a circuit as the voltage increases?
In a circuit, as the voltage increases, the current also increases, assuming the resistance remains constant, according to Ohm's Law (I = V/R). This relationship indicates that higher voltage pushes more electrons through the circuit, resulting in greater current flow. However, if the resistance changes, the effect on current may vary accordingly. In cases with non-linear components, the relationship between voltage and current can be more complex.
Will voltage or current be higher in a circuit during short circuit?
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
What is the relationship between current and resistance in a circuit when the voltage is kept constant?
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
