The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A)
Ohm's Law requires you know two of three parameters to calculate the third.Volts = Amps x OhmsYou need to know current flowing through resistance to calculate voltage drop.Read more: What_will_be_the_voltage_drop_across_each_of_the_following_resistors_A_160_Ohms_B_100_Ohms_C_82_Ohms_D_120_Ohms.
Ohm's law is V = I·R. You know V and I, so you can calculate R using R = V/I.60 V / 2 A = 30 Ω
A current shunt is a device with a very low resistance, usually around one ohm. The exact resistance of the shunt is printed on the device for reference, and it is often slightly higher or lower than nominal, for example a 1 ohm shunt may actually have a resistance of .99986 ohms or 1.0002 ohms. A current shunt is not used to control current, however, so I do not know if this is the device you are asking about. It is used to measure current by using a precision voltmeter to measure the voltage drop across the shunt, and then using ohms law to calculate the current. Voltage (Volts) divided by Resistance (Ohms) equals Current (Amps). When the shunt is placed so that it interrupts a circuit, (placed in series), the current flowing in the circuit can be accurately measured with the shunt, without changing the values in the circuit enough to affect it. Many shunts of this type have a large heavy duty resistor that does not overheat easily. The shunt should also have a max current rating listed on it.

You need to know the resistance. Ohm's Law: Current = Voltage (in volts) divided by resistance (in ohms).
Ohm's Law requires you know two of three parameters to calculate the third. Volts = Amps x Ohms You need to know current flowing through resistance to calculate voltage drop.
To calculate the voltage across a 600-ohm resistor, you also need to know the current passing through it. Using Ohm's Law (V = I * R), where V is the voltage, I is the current, and R is the resistance, you can determine the voltage.
To calculate the current in the parallel circuit we need the concept of ohms law, V=IR we know the resistance, R=48 ohms voltage will be constant as 220-230 volts so, I= V/R = 230/48 = 4.791 A Add currents of three lamps, ie., I = 14.375

To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
if current and resistance are know are known then voltage can be calculated using OHMS LAW V=I*R 2*16= 32 Volt
Ohm's law is V = I·R. You know V and I, so you can calculate R using R = V/I.60 V / 2 A = 30 Ω
To calculate the resistance in ohms, you also need to know the voltage. The formula to find the resistance in ohms is R = V^2 / P, where R is the resistance in ohms, V is the voltage, and P is the power in watts.
To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.
