What is the unit of measurement for electric current?
The unit of measurement for electric current is the ampere (A).
If your cell phone charger had too high of a current, you could add a resistor so that it doesn’t burn out your battery. How does a resistor work?
A resistor is an electronic component that resists the flow of electrical current. It does this by limiting the amount of current that can pass through the circuit. When a resistor is added to a circuit, it reduces the current flowing through the circuit, which helps protect other components from being overwhelmed by too much current. Resistor also helps to control the amount of voltage and current in a circuit, and can be used to divide voltage, limit current, adjust signal levels, and perform many other functions in electronic circuits.
If your cell phone charger had too high of a current, you could add a resistor so that it doesn’t burn out your battery. How does a resistor work? (short answer)
A resistor works by limiting the flow of electrical current in a circuit, helping to protect components from receiving too much current and preventing damage.
does a higher voltage result in a higher or a lower current?
A higher voltage typically results in a higher current in a circuit, as described by Ohm's Law (I = V/R), where current (I) is directly proportional to voltage (V) when resistance (R) is constant. Therefore, an increase in voltage will generally lead to an increase in current flow in a circuit.
does a higher resistance result in a higher or a lower current?
A higher resistance typically results in a lower current in a circuit, as described by Ohm's Law (I = V/R), where current (I) is inversely proportional to resistance (R) when voltage (V) is constant. Therefore, an increase in resistance will generally lead to a decrease in current flow in a circuit.
