Clear the circuit diagram and make a new circuit. Set the voltage of the battery to 9 V, set up a series circuit with three resistors. Set one resistor to 10 Ohms, the second resistor to 21 Ohms, and the third resistor to 13 Ohms. What is the equivalent resistance? What is the average current across the circuit?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
