Voltage = Current x Resistance
giving us
Current = Voltage / Resistance
i.e. Voltage divided by resistance
Ohm's Law: E = I*R : Voltage (or Potential Difference) = Current times Resistance.
So Resistance = (Potential Difference) / Current
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
There is insufficient information in the question to properly answer it. You need to specify, also, the voltage, in order to determine resistance from current. Please restate the question. Ohm's Law: Resistance = voltage divided by current.
A: Checking continuity is the same as checking resistance, therefore yes someone can determine the resistance at that particular current level
A multimeter device can measure resistance, current, AC/DC voltage, and it also can determine continuity on an electrical circuit, and its range for current, voltage and resistance is widely variable.
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.

You use an ohmeter. It sends current through the wire to determine value.
You can measure the emf of a cell by using a voltmeter, as this draws current from a cell. You can use the voltage, the emf, and the load resistance to determine the internal resistance of the cell.

Resistance is measured in ohms and the amount of resistance that allows one ampere of current to flow when one volt is applied is one ohm.

to determine the comparison of resistance value of both forward and reverse diode . The more the resistance the lower the current , the lower the resistance the higher the current . When reverse bias , the resistance is high and it acts in open circuit and the reverse current is very small that can be neglected . When forward bias , the resistance is low and it acts as short circuit and the forward current is increasing as the voltage supply is higher .
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
