Milk quality determines cheese quality, expect cheese to turn out only as good as the milk with which it begins.

Cheese is:

A parallel circuit has two branches with R1 = 20 , R2 = 20 , connected to a 100 V source.  Calculate the Current flowing through the R1 branch.

Salt’s effects on cheese-making:

A parallel circuit has two branches with R1 = 20 , R2 = 20 , connected to a 100 V source.  What is the Voltage across R2 ?

If an MRI machine has a field strength of 1.5 Tesla, how many Gauss is this?

A series circuit has three resistors: R1 = 10 , R2 = 20 , and R3 = 30 , with a total voltage of 120 V. Calculate the Total Resistance (Rt).

Unit Conversion: Convert 125 kVp to Volts.

A heating element produces 400 W of power with a current of 2 A. What is its resistance?

If the voltage in a circuit is doubled while the resistance remains constant, what happens to the current?
