A parallel branch is a current path. In general, current follows paths, voltage drops across components, and resistance is the voltage divided by current of specific circuit elements.

What is resistance on something that is shorted?
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
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.
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
What is the equivalent resistance through the enire circuit of 90 volts?
Not enough information. In the case of simple circuits, usually you would add resistances that are in series, and use a slightly more complicated formula for resistance that are in parallel. You CANNOT determine an equivalent resistance known only the voltage. However, if you know the total current, you can divide the voltage by the total current to get the equivalent resistance.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.

How amount of electrical current that can flow through a circuit depends on what?
The potential difference (voltage) between the ends of the branch, and the resistance of the branch. In a simple parallel circuit, the voltage is usually the full power supply, so the main thing to note is that none of the other parallel branches has any influence on the current through the parallel branch of interest.

How do you increase resistance?
Since resistance is the ratio of voltage to current, if the voltage is constant then increasing the resistance will result in a reduction in current.

What is a term for the relationship of voltage current and resistance in a simple electrical circuit?
Ohm's Law. According to Ohm's law V = iR where V is voltage (usually measured in volts) between two points of the circuit i is current (usually measured in amperes) between two points of the circuit R is resistance (usually measured in Ohms) between two points of the circuit.

What type of circuit has little to no resistance and will usually blow a fuse?
there are three types of circuits. Series,parallel,parallel-series. Series circuits usually are involved with dimming lights, and blown fuses.
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
What causes heating effect when current flows?
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
Would a multimeter connected in parallel as part of the circuit measure current or power consumption or voltage or wattage?
A typical multimeter measures voltage and resistance "in parallel" or current in-line with the circuit. It all depends on the model. 'Multi' means many different modes. Some have more than others. Some multimeters can measure current, but require you to alter the lead configuration and plug into different sockets. If you have the meter set for Current measurement and you put it in parallel instead of series, it will cause a dead short and could damage the meter. (They usually have a fuse inside for protection). Knowing any two of the three parameters you can calculate the third by Ohm's Law: Voltage = Current x Resistance. Knowing Current and Voltage you can calculate power as Volts x Amps = Watts for resistance loads.
