An AC source operating at 60 Hz with a maximum voltage of 162 V is connected in series with a resistor ($R = 1.6 k\Omega$) and a capacitor ($C = 2.5 \mu F$). (a) What is the maximum value of the current in the circuit? 0.08438 A (b) What are the maximum values of the potential difference across the resistor and the capacitor? $\Delta V_{R, max} = 135 V$ $\Delta V_{C, max} = 89.4 V$ (c) When the current is zero, what are the magnitudes of the potential difference across the resistor, the capacitor, and the AC source? $\Delta V_R = $ $\Delta V_C = $ $\Delta V_{source} = $ How much charge is on the capacitor at this instant? 224 $\mu C$ (d) When the current is at a maximum, what are the magnitudes of the potential differences across the resistor, the capacitor, and the AC source? $\Delta V_R = $ $\Delta V_C = $ $\Delta V_{source} = $ How much charge is on the capacitor at this instant? $\mu C$

Politics and economics are set to collide over welfare payments in the world's most unequal nation. The first clue over which will prevail may come in South African President Cyril Ramaphosa's State-Of-TheNation address on Thursday. Record unemployment and deepening poverty has fuelled calls for the government to move toward a basic income grant, which would be the biggest of its kind globally, or to at least extend a temporary stipend of 350 rand (\$23) a month paid to the unemployed during the pandemic permanent at that level or slightly higher. That measure added 10.3 -million people to the welfare net. Suppose that the South African Economy is in a recession, the policy response in the extract above would be inline with which of the following schools of economic thought? A. Monetary economics B. Classical theorists C. Keynesian theory D. Marxists economics

1) [5 points] Consider the large open economy model of current account determination. Imagine that in an attempt to fight persistent budget deficit, foreign government imposes a tax on investment, with tax proceeds being spent on the reduction of government debt. Using Metzler diagram (and providing a couple of sentences of explanation), show what happens to equilibrium savings, investment, current account and interest rate in both home and foreign country. Explain whether the effect of the policy on the variables of interest is ambiguous or not.
