Question

Read two doubles as the voltage and the current of a wire object. declare and assign pointer mywire with a new wire object using the voltage and the current as arguments in that order. then call mywire's increasevoltageandcurrent() member function. ex: if the input is 1.5 4.0, then the output is:

Answer 1

The question involves a programming exercise related to physics, specifically Ohm's law. If a wire object's function doubles both voltage and current, it implies constant resistance in the circuit, resulting in a doubled current when voltage is doubled.

Step-by-step explanation:

The question pertains to the physics concept of Ohm's law, which describes the relationship between voltage, current, and resistance in an electrical circuit. When a student is asked to read two doubles as the voltage and the current of a wire object and then call a function to increase both, they are likely working with a hypothetical wire class in programming that simulates this physical law.

According to Ohm's law, the current through a conductor between two points is directly proportional to the voltage across the two points. Therefore, if we assume the wire object's increaseVoltageAndCurrent() member function doubles both the voltage and current, it implies that the resistance stays constant. If the input is 1.5 volts for the voltage and 4.0 amperes for the current, after calling the increaseVoltageAndCurrent() function, both the voltage and current would double if the wire object behaves as an ohmic resistor. This means the new values would be 3.0 volts and 8.0 amperes respectively.

Two doubles are read as the voltage and the current of a Wire object. Declare and assign pointer myWire with a new Wire object using the voltage and the current as arguments in that order.

Ex: If the input is 4.5 1.0, then the output is:

Wire's voltage: 4.5 Wire's current: 1.0

#include <iostream>

#include <iomanip>

using namespace std;

class Wire {

public:

Wire(double voltageValue, double currentValue);

void Print();

private:

double voltage;

double current;

};

Wire::Wire(double voltageValue, double currentValue) {

voltage = voltageValue;

current = currentValue;

}

void Wire::Print() {

cout << "Wire's voltage: " << fixed << setprecision(1) << voltage << endl;

cout << "Wire's current: " << fixed << setprecision(1) << current << endl;

}

int main() {

Wire* myWire = nullptr;

double voltageValue;

double currentValue;

cin >> voltageValue;

cin >> currentValue;

/* Your code goes here */

myWire->Print();

return 0;
