Answer:
5 significant figures
Explanation:
The current in a circuit is governed by voltage and resistance, as dictated by Ohm's Law. The voltage-current relationship can be linear in ohmic materials or nonlinear in non-ohmic materials.
The current flowing in a circuit depends primarily on two variables: voltage and resistance. This relationship is defined through Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R), or I=V/R.
When the voltage increases while the resistance remains constant, the current will increase. Conversely, when the resistance increases while the voltage remains constant, the current will decrease. Thus, for example, if the resistance doubles, the current is cut in half.
However, it is important to note that not all materials follow this linear relationship. Some materials, known as ohmic materials, follow Ohm's Law, while others, known as non-ohmic materials, exhibit a nonlinear voltage-current relationship.
