Is this true or false the more cells there are in a circuit the bigger the push and the current?

False. The number of cells in a circuit does not inherently increase the current; instead, it typically increases the voltage. Current is influenced by both voltage and resistance in the circuit according to Ohm's Law (I = V/R). However, adding more cells in series raises voltage, which can lead to a higher current if the resistance remains constant.


In RC circuits the voltage leads the current?

Inductive. Used to remember this by "Eli" the "ice" man. "(e) Voltage (l) (Inductive circuit) (i) current", the ,"(i) Current (c) (capacitive circuit) (e) voltage, man.


Is Ohm's law states that voltage in a circuit is equal to resistance times current true or false?

True. Ohm's law states the voltage is resistance times current.


In an electric circuit the ground prevents current from flowing in the circuit true or false?

In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.


True or false if the voltage and resistance of a circuit stay constant the amperage can never change?

The equation for the three values in the question will give the definite answer.Amperage (I) is equal to the voltage (E) divided by the resistance (R).I= E / R So as you can see the answer is True.Example: 10 Volts and 50 Ohms in a circuit will have a current of .2 Amperes flowing through it. 10 / 50 = .2You can also rearrange the equation to find the other two:E= R * ER= E / I


What is voltage level of RS-232?

RS-232 is ±3 to ±15, with a maximum short circuit survivability rating of ±25. Typical implementations see ±12. The negative voltage is the marking state, or the one state at the USART level. The positive voltage is the spacing state, or the zero state at the USART level. In terms of control signals, such at DTR or CTS, MARK (negative) is false, and SPACE (positive) is true. Zero volts is invalid, representing a break state.


In a circuit where true is logic 0 and false is logic 1 the logic is said to be logic?

In a circuit where true is represented by logic 0 and false by logic 1, the logic is referred to as "inverted" or "negative logic." This means that the conventional interpretation of truth values is reversed, with low voltage levels indicating true and high voltage levels indicating false. This approach can be useful in certain digital systems and simplifies the design of certain types of circuits, particularly in memory and logic gate implementations.


Can 2 cells push electric current harder round a circuit?

No, cells do not push electric current harder around a circuit. Electric current is driven by the voltage difference between the cells. Adding more cells in series increases the voltage, which can result in more current flowing through the circuit, but the cells themselves do not push the current harder.


In an electric circuit the ground prevents current from flowing in the circuit.?

false


If one light bulb is removed from a parallel circuit with three bulbs the brightness of the other bulbs will decrease True or false?

False. In a parallel circuit, each light bulb operates independently, so removing one bulb does not affect the brightness of the others. The remaining bulbs will continue to receive the same voltage as before, maintaining their brightness.


Can NCO's receiving all success rating receive a rating of among the best?

FALSE
