Calculation using Ohm's Law: If a circuit has a voltage of 500 V and a resistance of 250 ohms, what is the current?
konstantin123 [22]

I = V / R

Current = (voltage) / (resistance)

Current = (500 V) / (250 ohms)

Current = (500/250) Amperes

<em>Current = 2 Amperes</em>

What does a dielectric do to a capacitor?
Leto [7]

A dielectric fabric is used to split the conductive plates of a capacitor. This insulating cloth significantly determines the properties of a component. The dielectric constant of fabric determines the amount of strength that a capacitor can keep while voltage is applied.

A capacitor is an electrical component that attracts energy from a battery and stores the power. Internal, the terminals connect with metal plates separated by way of a non-engaging in substance. While activated, a capacitor quickly releases electricity in a tiny fraction of a 2d.

Capacitor, a tool for storing electric electricity, together with two conductors in near proximity and insulated from each different. A simple example of this sort of garage tool is the parallel-plate capacitor.

A capacitor is a tool that shops electric power in an electric-powered area. it is a passive digital thing with terminals. The effect of a capacitor is called capacitance.

¿que es hipótesis?¿que es teoría?​
Ludmilka [50]

Answer:

The hypothesis is only an assumption that has not yet been proven, when it has been tested, and it cannot be shown that it is false, then it is no longer a simple hypothesis, it is a Theory. Hypothesis is when we raise a supposed result. Theory is the result of an experiment.

What determines what will be tested in a scientific experiment
Artyom0805 [142]
What you want to test and your hypothesis does.
For example, say you came up with a hypothesis that 'The higher the temperature, the higher the reaction rate will be'.
Your independent variable (the one you change) will be temperature. The dependent variable (the one that changes because of the independent) will be the reaction rate (e.g. bubbles produced).
