What is the shortcut on solving problems that deal with ohms law?
calculate the current in a 140-w electric blanket connected to a 120-v outlet

Ohm's Law is a fundamental principle in physics that describes the relationship between electric current, voltage, and resistance. It states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance.
The formula for Ohm's Law is I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
A short-cut for Ohm's Law is using the triangle method, also known as the EIR triangle. This method allows you to quickly solve for current, voltage, or resistance by covering up the variable you want to solve for and using the remaining two variables in the formula.
To use the EIR triangle, cover up the variable you want to solve for and use the remaining two variables to determine the value. For example, if you want to solve for current, cover up the I in the triangle and use V/R to find the value. If you want to solve for voltage, cover up the V and use I*R, and if you want to solve for resistance, cover up the R and use V/I.
Yes, Ohm's Law can be used for any type of circuit, as long as the circuit follows Ohm's Law principles. This includes circuits with resistors, capacitors, and inductors. However, for more complex circuits, additional laws and principles may need to be applied.
