Final answer:

True, the formula I = E/R is correct according to Ohm's Law, which defines the relationship between current (I), voltage (V or E), and resistance (R) in an electrical circuit.

Step-by-step explanation:

The statement 'The basic Ohm's Law algebraic formula for current is: I = E/R' is true. Ohm's Law is a fundamental concept in Physics that explains the relationship between current (I), voltage (V or E in some texts), and resistance (R) in a simple circuit. The formula you've mentioned uses E to denote electromotive force or voltage. Therefore, when you know the voltage and resistance, you can calculate the current using the formula I = V/R (where V is the voltage). This is an algebraic rearrangement of the more commonly seen form of Ohm's Law, which is V = IR, expressing that voltage is equal to current multiplied by resistance. These equations demonstrate that the current is directly proportional to the voltage and inversely proportional to the resistance.

Ohm's law is crucial in designing and analyzing electrical circuits since it allows for the calculation of one quantity if the other two are known. The law is only strictly applicable to ohmic materials, which exhibit a linear relationship between voltage and current, meaning their resistance remains constant across various voltages.

An ohmmeter is an instrument that exemplifies this principle. It applies a known voltage to a resistor, measures the current that flows through it, and calculates the resistance using Ohm's law.
